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.
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
introductionGastroesophageal reflux is a major problem after sleeve gastrectomy. There is still insufficient understanding of how it occurs and whether it is due to the sphincter length, relaxation, or pressure differences.
aimThis study evaluates the effect on the lower esophageal sphincter of the laparoscopic sleeve gastrectomy (LSG) technique applied in surgery in cases of morbid obesity using ambulatory 24-h pH monitoring (APM) and esophageal manometry (EM). MATERIAL AND
methodsA retrospective examination was carried out on the APM and EM tests performed preoperatively and postoperatively in cases of LSG. The parameters examined were the body mass index (BMI), amplitude pressure of the esophagus (AP), total length of the lower esophageal segment (LESL), resting pressure of the LES (LESP), residual pressure of the LES (LESR), relaxation time of the LES, intragastric pressure, and the DeMeester score.
resultsA total of 62 cases with available data were evaluated. A statistically significant difference was determined between the preoperative values and the 3-month postoperative values of BMI, LESP, and relaxation time of the LES. A statistically significant increase was determined in the DeMeester score, and the increase in the total number of reflux episodes longer than 5 min was found to be the most responsible for this increase. No significant difference was determined in the other parameters.
conclusionsThe LSG was found to cause a reduction in LESP, and an increase in acid reflux causing an extended relaxation time of the LES. This was confirmed by the increase seen in the DeMeester score.
