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

backgroundIn metabolic bariatric surgery (MBS) a lot of focus is made on preoperative risk assessment to enhance patient's baseline performance and improve postoperative clinical outcomes. The aim of this study is to assess pre-operative sarcopenia by computed tomography (CT) scan, as a predictive tool for early post-operative complications in candidates for MBS.

methodsThis is a single center prospective case-control study. The study includes using non-contrast CT cuts at L3 vertebra level to measure total abdominal muscle area (TAMA) and visceral fat area (VFA). TAMA was indexed to the patient height and VFA/TAMAI ratio was estimated. Models for predicting postoperative complications were made for TAMA alone, TAMAI alone, VFA alone and VFA/TAMAI ratio to assess each factor's reliability in predicting postoperative complications.

resultsThe study enrolled 30 patients who underwent laparoscopic sleeve gastrectomy (LSG); 14 experience early post-operative complications in the cases arm, matched against 16 in the control arm. TAMA and TAMAI showed a significant association with early post-operative complications.

conclusionOur findings suggest that TAMA and TAMAI, measured by non-contrast CT as markers for sarcopenia, may be associated with early post-operative complications for laparoscopic sleeve gastrectomy (LSG) patients.
