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

backgroundTo demonstrate the lack of utility and efficacy of routine early postoperative upper gastrointestinal study (UGI) in obese patients undergoing bariatric surgery and to show the higher efficacy of CT scan in cases of clinical suspicion of a leakage, a meta-analysis was performed. MATERIALS AND

methodsA literature search including articles published in last 18 years was performed. For both UGI and CT scan, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated. A first analysis considered overall patients, and a second analysis considered only symptomatic patients.

resultsStarting from 1233 eligible citations, 18 articles, including 7516 patients, were left. The pooled sensitivity was 54% for UGI (95% CI 34-74) with a high heterogeneity (I

conclusionsAccording to our results, a CT scan triggered by clinical suspicion must be considered the first-line procedure to detect a postoperative leak following primary sleeve gastrectomy or Roux-en-Y gastric bypass.
