Maternal Roux-en-Y gastric bypass impairs insulin action and endocrine pancreatic function in male F1 offspring.
Article in European journal of nutrition, 2020. 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
purposeObesity is predominant in women of reproductive age. Roux-en-Y gastric bypass (RYGB) is the most common bariatric procedure that is performed in obese women for weight loss and metabolic improvement. However, some studies suggest that this procedure negatively affects offspring. Herein, using Western diet (WD)-obese female rats, we investigated the effects of maternal RYGB on postnatal body development, glucose tolerance, insulin secretion and action in their adult male F1 offspring.
methodsFemale Wistar rats consumed a Western diet (WD) for 18 weeks, before being submitted to RYGB (WD-RYGB) or SHAM (WD-SHAM) operations. After 5 weeks, WD-RYGB and WD-SHAM females were mated with control male breeders, and the F1 offspring were identified as: WD-RYGB-F1 and WD-SHAM-F1.
resultsThe male F1 offspring of WD-RYGB dams exhibited decreased BW, but enhanced total nasoanal length gain. At 120 days of age, WD-RYGB-F1 rats displayed normal fasting glycemia and glucose tolerance but demonstrated reduced insulinemia and higher glucose disappearance after insulin stimulus. In addition, these rodents presented insulin resistance in the gastrocnemius muscle and retroperitoneal fat, as judged by lower Akt phosphorylation after insulin administration, but an increase in this protein in the liver. Finally, the islets from WD-RYGB-F1 rats secreted less insulin in response to glucose and displayed increased β-cell area and mass.
conclusionsRYGB in WD dams negatively affected their F1 offspring, leading to catch-up growth, insulin resistance in skeletal muscle and white fat, and β-cell dysfunction. Therefore, our data are the first to demonstrate that the RYGB in female rats may aggravate the metabolic imprinting induced by maternal WD consumption, in their male F1 descendants. However, since we only used male F1 rats, further studies are necessary to demonstrate if such effect may also occur in female F1 offspring from dams that underwent RYGB operation.
