Migrating contractions of the afferent and Roux limbs show peristaltic movement independently of each other in conscious dogs after Roux-en-Y reconstruction after distal gastrectomy.

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 Roux-en-Y (RY) procedure is used frequently for surgical reconstruction after gastrectomy. However, a minority of patients suffer a serious motility disorder of the Roux and afferent limb postoperatively. We conducted this study to clarify the association between the motility and peristaltic direction of two limbs in conscious dogs.
methodsWe performed distal gastrectomy on five dogs and implanted seven force transducers on the serosal surfaces of the remnant gastric body and afferent and Roux limbs. We then analyzed the electric signals from these force transducers.
resultsMigrating contractions were observed in the two limbs, but not in the gastric remnant body. Migrating contractions in the forward direction propagated independently from the most proximal side in each limb. There was no propagation of contraction across the jejunojejunostomy between the two limbs.
conclusionsEach proximal part of the Roux and afferent limbs has an independent motility pacemaker in conscious dogs after gastrectomy with RY reconstruction.
