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
introductionOne anastomosis gastric bypass (OAGB) offers favourable weight loss outcomes and is associated with reduced morbidity and mortality when compared to other mainstream bariatric procedures. However, a randomised trial reported a conversion rate to roux-en-Y configuration (RYC) of 3.1%, and some surgeons consider the procedure unsuitable for patients with a preoperative hiatus hernia (HH) or symptoms of gastrooesophageal reflux disease (GORD).
methodsWe carried out a retrospective review of patients undergoing OAGB in our institution. Included were all patients on PPI for symptoms of GORD preoperatively, as well as patients with HH or oesophagitis on preoperative endoscopy. We recorded GORD outcomes as well as rates of conversion to RYC in patients.
resultsMedium term follow up data at 23-28 months was available for 89 patients. Of these, 63 had HH, 34 had preoperative GORD requiring PPI and 9 had confirmed oesophagitis. The conversion rate to RYC was nil (0/63) in patients with HH. At the same time, 14.7% (5/34) of patients with preop GORD on PPI required conversion to RYC at a median time interval of 16 months. In patients already on PPI preoperatively, 16/34 (47.1%) needed to continue on PPI long term. In patients with HH, 20.6% (13/63) suffered de novo GORD symptoms.
conclusionOAGB can be offered to patients with HH with acceptable GORD outcomes but caution is advised in patients with preoperative GORD symptoms. Larger prospective and randomised studies are required to further assess this subgroup.
