Gastric Emptying and Food Tolerance Following Banded and Non-banded Roux-en-Y Gastric Bypass.
Trial report in Obesity surgery, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
introductionGastric emptying (GE) and food tolerance (FT) can be altered after Roux-en-Y gastric bypass (RYGB) has been performed, especially when it involved the use of a restrictive mechanism (such as a silastic ring).
aimTo assess GE and FT in patients who underwent banded (BRYGB) or non-banded Roux-en-Y gastric bypass (RYGB).
methodsForty-seven BRYGB patients and 47 RYGB patients underwent gastric emptying scintigraphy (GES) and FT assessment (by means of a questionnaire) between 6 months and 2 years postoperatively.
resultsGES was performed on average 11.7 ± 5.0 months (6 to 24) postoperatively. T½ medians (time taken for the gastric radioactivity to decrease to half of the original value in the gastric pouch) in the RYGB and BRYGB groups were 48.7 min (40.6-183.0 min) and 56.3 min (41.1-390.9 min), respectively (p = 0.031). The median of total questionnaire scores was 24 points (18-27) in the RYGB group and 20 points (13-27) in the BRYBG group (p < 0.001).
conclusionsThe band (silastic ring) delays GE time and does not affect patient satisfaction or food tolerance to vegetables, bread, or rice, but does affect tolerance to the intake of meat, salad, and pasta. The best tolerated foods are vegetables, salad, and fish. Banded patients are more likely to regurgitate and vomit. Gastric emptying does not affect FT.
