Abdominal pain and symptoms before and after Roux-en-Y gastric bypass.
Trial report in BJS open, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 17 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
Background: Despite increased emphasis on patient-reported outcomes, few studies have focused on abdominal pain symptoms before and after Roux-en-Y gastric bypass (RYGB). The aim of this study was to quantify chronic abdominal pain (CAP) in relation to RYGB. Methods: Patients with morbid obesity planned for RYGB were invited to participate at a tertiary referral centre from February 2014 to June 2015. Participants completed a series of seven questionnaires before and 2 years after RYGB. CAP was defined as patient-reported presence of long-term or recurrent abdominal pain lasting for more than 3 months. Results: A total of 236 patients were included, of whom 209 (88·6 per cent) attended follow-up. CAP was reported by 28 patients (11·9 per cent) at baseline and 60 (28·7 per cent) at follow-up ( Conclusion: The prevalence of CAP is higher 2 years after RYGB compared with baseline values.
