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

backgroundSleeve gastrectomy (SG) is a common metabolic and bariatric surgery (MBS) with conflicting effects on gastroesophageal reflux disease (GERD), with some patients improving and others experiencing new or worsened GERD. This study investigated whether preoperative ambulatory 24-h pH monitoring (24-h pH) predicts postoperative GERD in patients undergoing SG, comparing GERD outcomes among those with normal, abnormal, and without preoperative 24-h pH.

methodsA retrospective study was conducted on 120 patients (88.3% women, 38 ± 9 years, preoperative BMI 38.0 [36.4-40.6] kg/m

resultsAt 12 months, the groups had a similar proportion of normal UGIE findings. Grade B esophagitis occurred in 7.5% of the NG vs. 25% of the AG. The NG exhibited lower Gerd-Q total scores and a smaller proportion of positive results compared with the NMG and the AG (2 [0-5] vs. 7 [0.5-18] and 5 [2-11.75]; 12.5% vs. 47.5% and 47.5%, respectively; p < 0.05 for all variables).

conclusionPostoperative GERD was more frequent in patients with abnormal or those without preoperative 24-h pH monitoring, whereas those with normal results in this test exhibited lower rates. These findings raise an important discussion regarding the role of 24-h pH monitoring before SG and its impact on clinical decision-making.
