1 · What the graph read from it

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.

2 · The registry

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

backgroundSubtotal cholecystectomy (SC) is a useful procedure for avoiding bile duct injury in patients with difficult gallbladder. However, risk factors for conversion to SC, especially preoperative magnetic resonance cholangiopancreatography (MRCP) findings that predict conversion to SC, have not been investigated in detail.

methodsA total of 290 patients with acute cholecystitis who underwent laparoscopic cholecystectomy at our hospital between November 2011 and March 2020 were included. Patient characteristics and perioperative outcomes were reviewed, and preoperative clinical factors predicting conversion to SC were investigated.

resultsForty-three patients underwent SC, whereas the remaining 247 patients underwent total cholecystectomy. An American Society of Anesthesiologists (ASA) score of 3 or greater (p = 0.011), surgery on or after 9 days from symptom onset (p < 0.001), obscuration of the gallbladder wall around the neck on MRCP images (p = 0.010) and disruption of the common hepatic duct on MRCP images (p < 0.001) were significantly associated with conversion to SC. Logistic regression analyses revealed that an ASA score of 3 or greater (odds ratio = 2.667, p = 0.020), surgery on or after 9 days from symptom onset (odds ratio = 4.229, p < 0.001) and disruption of the common hepatic duct on MRCP images (odds ratio = 4.478, p = 0.002) were independent predictors for conversion to SC.

conclusionsEarly surgery yielded a lower risk for conversion to SC. Disruption of the common hepatic duct on preoperative MRCP images is associated with a risk for conversion to SC.
