Evaluation of TU-100 (Daikenchuto), a Traditional Japanese Kampo Medicine, as an Adjunct to Enhanced Recovery After Surgery, for Acceleration of Gastrointestinal Recovery After Bowel Resection: Results of a Proof-of-Concept, Phase 2, Randomized, Double-Blinded, Placebo-Controlled Trial.
Trial report in Diseases of the colon and rectum, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04742907 (Randomized, Double-Blind, Placebo-Controlled, Phase 2 Trial to Evaluate the Safety and Efficacy of TU-100 as an Adjunct to an Enhanced Recovery After Surgery), which is not on this map.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract
backgroundA transient inhibition of GI motility (postoperative ileus) can occur after colorectal surgery and may lead to complications and prolonged hospitalization.
objectiveTo examine the effect of TU-100, a Japanese herbal medicine, on the acceleration of GI recovery after bowel resection.
designProof-of-concept, randomized, double-blinded, placebo-controlled phase 2 trial (NCT04742907). SETTINGS: Thirty-six US hospital sites. PATIENTS: Patients undergoing elective bowel resection.
interventionsPlacebo, TU-100 7.5 g/d, or TU-100 15 g/d given orally from postoperative day 1 for 10 days or less while hospitalized.
main outcome measuresThe primary end point was time to GI recovery, a composite representing upper (first toleration of clear liquids) and lower (first bowel movement or absence of distention and presence of bowel sounds and flatus) GI motility. Multiple GI- and discharge-related outcomes were also evaluated.
resultsA total of 392 patients received at least 1 dose. TU-100 7.5 g/d was not associated with a statistically significant difference for GI recovery (HR 1.17 [95% CI, 0.91-1.50]). However, a higher proportion of patients in the 7.5 g/d group achieved GI recovery by postoperative day 2 versus the placebo group (78.1% vs 66.9%, p = 0.047). Median length of stay was significantly shorter in the 7.5 g/d (2 days) vs placebo (3 days [ p = 0.03]) group. Patient-reported nausea and abdominal bloating bothersomeness were lower in the early postoperative period for 7.5 g/d versus placebo group. Overall, no significant differences between 15 g/d and placebo were noted. LIMITATIONS: Limited dosing and short evaluation window (short hospital stay).
conclusionsCompared with the placebo, TU-100 7.5 g/d was associated with consistent, encouraging trends in efficacy outcomes, including more patients achieving GI recovery by postoperative day 2, with fewer bothersome GI symptoms. A statistically significant difference in hospital stay was noted for patients receiving 7.5 g/d versus placebo, despite relatively short stays, with drug administration not begun until postoperative day 1, and used in conjunction with enhanced recovery after surgery pathways. Further studies are warranted. See Video Abstract . EVALUACIN DEL TU DAIKENCHUTO, UN MEDICAMENTO TRADICIONAL JAPONS KAMPO, COMO COMPLEMENTO PARA MEJORAR LA RECUPERACIN TRAS LA CIRUGA, CON EL FIN DE ACELERAR LA RECUPERACIN GASTROINTESTINAL TRAS UNA RESECCIN INTESTINAL RESULTADOS DE UN ENSAYO DE PRUEBA DE CONCEPTO, FASE II, ALEATORIZADO, DOBLE CIEGO Y CONTROLADO CON PLACEBO: ANTECEDENTES:Tras una cirugía colorrectal puede producirse una inhibición transitoria de la motilidad gastrointestinal (íleo posoperatorio) que puede dar lugar a complicaciones y prolongar la hospitalización.OBJETIVO:Examinar el efecto del TU-100, un medicamento a base de hierbas japonesas, en la aceleración de la recuperación gastrointestinal tras una resección intestinal.DISEÑO:Ensayo de fase II de prueba de concepto, aleatorizado, doble ciego y controlado con placebo (NCT04742907).ENTORNO:Treinta y seis centros hospitalarios de Estados Unidos.PACIENTES:Pacientes sometidos a resección intestinal electiva.INTERVENCIONES:Placebo, TU-100 7,5 g/día o TU-100 15 g/día por vía oral desde el primer día postoperatorio durante ≤10 días mientras permanecieran hospitalizados.PRINCIPALES MEDIDAS DE RESULTADO:El criterio de valoración principal fue el tiempo hasta la recuperación gastrointestinal, un compuesto que representa la motilidad gastrointestinal superior (primera tolerancia de líquidos claros) e inferior ([primera evacuación intestinal] o [ausencia de distensión y presencia de ruidos intestinales y flatulencia]). También se evaluaron múltiples resultados relacionados con el tracto gastrointestinal y el alta hospitalaria.RESULTADOS:Un total de 392 pacientes recibieron ≥1 dosis. TU-100 7,5 g/día no se asoció con una diferencia estadísticamente significativa en la recuperación gastrointestinal (razón de riesgo = 1,17 [IC del 95 %: 0,91, 1,50]). Sin embargo, una mayor proporción de pacientes del grupo de 7,5 g/día logró la recuperación gastrointestinal al segundo día después de la operación en comparación con el placebo (78,1 % frente a 66,9 %, p = 0,047). La duración media de la estancia fue significativamente más corta en el grupo de 7,5 g/día (2 días) que en el de placebo (3 días [ p = 0,03]). Las molestias por náuseas y distensión abdominal notificadas por los pacientes fueron menores en el periodo postoperatorio temprano con 7,5 g/día en comparación con el placebo. En general, no se observaron diferencias significativas entre 15 g/día y el placebo.LIMITACIONES:Dosificación limitada y ventana de evaluación corta (estancia hospitalaria corta).CONCLUSIONES:En comparación con el placebo, 7,5 g/día de TU-100 se asoció con tendencias consistentes y alentadoras en los resultados de eficacia, incluyendo un mayor número de pacientes que lograron la recuperación gastrointestinal al segundo día postoperatorio con síntomas gastrointestinales menos molestos. Se observó una diferencia estadísticamente significativa en la estancia hospitalaria para 7,5 g/día frente al placebo, a pesar de las estancias relativamente cortas, de que la administración del fármaco no se iniciara hasta el primer día postoperatorio y del uso con vías de recuperación mejorada después de la cirugía. Se justifican más estudios. ( AI-generated translations ).
