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

Recent research highlights TXA's potential in managing postoperative bleeding in bariatric surgery, prompting us to evaluate its effectiveness for treatment and prophylaxis. PubMed, Scopus, Cochrane Central, SciElo, and LILACS were searched for TXA studies in bariatric surgery, excluding those without control groups or with overlapping populations. Outcome analysis focused on postoperative bleeding, length of hospital stay (LOS), TXA side effects, mortality, transfusion needs, and thromboembolic complications. From 93 results, six studies involving 1121 patients were included. TXA use significantly decreased the LOS (MD = - 0.12; 95% CI, - 0.18, - 0.06; p < 0.01), operative time (MD = - 5.77; 95% CI, - 9.98, - 1.56; p < 0.01), and postoperative bleeding (OR = 0.57; 95% CI, 0.34, 0.98; p = 0.043). However, TXA did not affect the rate of hematoma formation (OR = 0.39; 95% CI, 0.07, 2.29; p = 0.299), rate of reoperation (OR = 0.46; 95% CI, 0.08, 2.82; p = 0.403), or need for transfusion (OR = 0.25; 95% CI, 0.06, 1.07; p = 0.062). There were no thromboembolic events or mortality. TXA significantly reduces LOS, operative time, and postoperative bleeding in bariatric surgery without affecting reoperation rates. This medication appears to be safe in this population as it did not increase the risk of thromboembolic events.
