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

backgroundLaparoscopic cholecystectomy is the gold-standard procedure for management of symptomatic gallstone disease. Increased rates of conversion to an open procedure, increased postoperative complications, and longer lengths of stay are seen in thick-walled gallbladders. Previous studies have only evaluated gallbladder walls as being thick or not thick, without looking at the degree of thickness. We hypothesized that, the more severe the wall thickening, the greater the chance of conversions and complications, and the longer the lengths of stay.

methodsAll attempted laparoscopic cholecystectomies in our institution between 2006 and 2009 were retrospectively reviewed. Patients undergoing cholecystectomy for reasons other than gallstones (e.g., polyps or cancer) and those without preoperative ultrasounds were excluded. Patients were divided into four groups based on the degree of gallbladder wall thickness: normal (1-2 mm), mildly thickened (3-4 mm), moderately thickened (5-6 mm), and severely thickened (7 mm and above). Outcomes were compared amongst the groups.

results874 patients were included in the study. There were 68 conversions (7.8 %) and 58 complications (6.6 %). The incidence of conversions was 3.1, 5.1, 14.9, and 16.8 % in the four groups, respectively (p < 0.001, χ (2)), and the incidence of complications was 1.8, 6.7, 9.1, and 13.1 %, respectively (p = 0.001, χ (2)). The mean (± standard deviation, SD) length of stay in days was 1.09 ± 1.42, 1.83 ± 3.24, 2.54 ± 3.40 and 3.54 ± 4.61, respectively [p < 0.001, analysis of variance (ANOVA)].

conclusionsA greater degree of gallbladder wall thickness is associated with an increased risk of conversion, increased postoperative complications, and longer lengths of stay. Classifying patients according to degree of gallbladder wall thickness gives more accurate assessment of the risk of surgery, as well as potential outcomes.
