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

backgroundDespite evidence on gallstone disease after laparoscopic sleeve gastrectomy (LSG), there is an existing lack of consensus on practice guidelines, i.e., surveillance and stone-lowering prophylaxis. Available evidence also has a racial bias as western reports predominate current data. Considering the growing popularity of LSG in Asia and the unique Asian anthropometrics, we have attempted to provide a regional perspective by reviewing our LSG database to investigate the epidemiology of this complication.

methodsOne hundred two morbidly obese cases were retrospectively reviewed. Abdominal ultrasounds were conducted preoperatively and at 12-month post-op. No gallstone-lowering prophylaxis was used. Outcome measure was the incidence of new gallstone formation at 1 year and the rate of symptomatic stones during the follow-up period.

resultsMean age was 43 years (range 20-68) with average initial BMI of 41.68 kg/m

conclusionOur results match western data in that gallstone formation is common after LSG though incidence of complicated stones is small. This is despite not using gallstone-lowering prophylaxis. The low conversion rate also questions the relevance of surveillance screening, as most patients with new gallstones remain asymptomatic at least in the short-term follow-up.
