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

backgroundThe measurement of weight loss after bariatric surgery is under constant review in order to obtain the ideal standard for reporting weight loss. Several formulas have been proposed for this purpose. Our goal is to analyse weight loss after sleeve gastrectomy, with or without antrum preservation through different measurement formulas.

methodsA prospective randomised study of 60 patients (30 patients with initial section at 3 cm from pylorus and 30 patients at 8 cm from the pylorus). We calculate the following variables at 3, 6 and 12 months from surgery: BMI, excess weight loss (%EWL), percentage of excess of BMI loss (%PEBMIL), expected BMI, % PEBMIL corrected by EBMI and percentage of total weight loss (%TWL).

resultsWeight evolution is similar in both groups, reaching a mean BMI of 33.62 ± 4.35 and 34.48 ± 4.23 kg/m

conclusionsGroup 3 cm obtained a lower percentage of suboptimal results using EWL. %TWL places the 3 cm group in higher percentile than 8 cm group. Through EBMI, both groups are equally effective. It is necessary to have standardised dynamic tables for each surgical technique, becoming essential elements to measure weight loss after surgery.
