Assessment of modified textbook outcomes following gastrectomy based on survival benefits: a multicenter observational study.
Observational study in International journal of surgery (London, England), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundTextbook outcome (TO) is an increasingly utilized metric for evaluating perioperative treatment quality. However, a standardized and universally accepted definition of TO in gastrectomy has not yet been established. This multicenter study aimed to evaluate the incidence of a modified definition of TO (mTO) and its association with long-term oncologic survival following gastrectomy.
methodsData from all consecutive patients undergoing curative-intent resection for gastric cancer were analyzed from institutional databases of seven high-volume centers in China between 7 January 2010, and 30 September 2019. The achievement rates of TO and mTO were measured. mTO was defined as achieving all of the following: pR0 resection, retrieval of at least 15 lymph nodes, absence of severe postoperative complications (Clavien-Dindo grade ≥IIIa) within 90 days, length of hospital stay below the 75th percentile, no 90-day mortality, and no 90-day readmission. The primary outcomes were the associations between mTO and 5-year overall survival (OS) and disease-free survival (DFS). The secondary outcome was to determine the rate of mTO and identify independent factors associated with its achievement.
resultsAmong 2608 eligible patients, the rates of mTO and TO were 62.4% (1628 patients) and 72.0% (1877 patients), respectively. Achieving mTO was independently associated with reduced hazards of death in Cox regression analysis for 5-year OS and DFS (HR 0.565 [95% CI: 0.504-0.633] and HR 0.561 [95% CI: 0.502-0.628], respectively). Similarly, achieving TO was independently associated with reduced hazards of death for 5-year OS and DFS (HR 0.737 [95% CI: 0.653-0.831] and HR 0.735 [95% CI: 0.65-0.827], respectively). Subgroup analyses demonstrated that mTO was consistently associated with a greater reduction in death hazards compared to TO for both OS and DFS.
conclusionmTO serves as a more comprehensive and beneficial indicator for assessing perioperative quality, providing superior survival benefits compared to TO.
