Hiatal Hernia Evaluation Before Bariatric Surgery: Should It Be Routinely Done?
Article in Obesity surgery, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
purposeThe necessity of routine preoperative esophagogastroduodenoscopy (EGD) and upper gastrointestinal series (UGIS) in the evaluation of hiatal hernia (HH) among bariatric surgery candidates is controversial since most are detected during surgery, regardless of the preoperative work-up. The aim is to determine the accuracy of preoperative EGD and UGIS for HH diagnosis among bariatric surgery candidates. MATERIAL AND
methodsThe records of bariatric surgery patients between 2011 and 2015 were reviewed. Patients underwent routine UGIS and/or EGD before the surgery. The positive and negative predictive values (PPV, NPV) for each study were calculated based on operative findings.
resultsA total of 463 patients were included in the study. Mean age was 44.34 ± 12.99 years. Mean preoperative body mass index (BMI) was 42.7 ± 5.15 kg/m
conclusionsBoth EGD and UGIS, whether solely performed or combined, have low sensitivity for diagnosis of HH and can probably be omitted from the preoperative evaluation, except for high-risk patients.
