Should lactate be added to Tokyo criteria for the evaluation of patients with acute cholangitis?
Article in Irish journal of medical science, 2022. 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
backgroundTokyo guidelines (TG13/18) are used for the severity assessment of acute cholangitis (AC). Lactate is a clinical marker of tissue hypoxia and disease severity, independent from blood pressure.
aimThe aim of this study is to investigate the relationship between blood lactate level and TG13/18 criteria in patients diagnosed with AC.
methodsOne hundred fifteen patients with AC were included in this retrospective study. Demographic characteristics of the patients and laboratory data were scanned from their hospital medical records. According to TG13/18 guidelines, the patients were divided into 3 groups as mild (grade 1), moderate (grade 2), and severe (grade 3) AC.
resultsSixty three (54.7%) of the patients were grade 1, 37 (32.1%) were grade 2, and 15 (13.0%) were grade 3. It was found that blood lactate level increased significantly from grade 1 to grade 3 (p < 0.001). In logistic regression analysis, white blood cell (WBC) count, total bilirubin and blood lactate levels independently determined the patients to be grade 2 or 3 AC. When the blood lactate cut-off value was taken as 16.5 mg/dL, we diagnosed grade 2 or 3 AC with a sensitivity of 78.8% and a specificity of 75.7%. From among lactate, WBC, and C reactive protein, lactate showed the highest value regarding the area under the curve, which is an index for predicting grade III upon ROC analysis.
conclusionThe blood lactate level is associated with the severity of AC. In addition to TG13/18 guidelines, blood lactate level can be a useful biomarker in the severity grading of AC.
