Prevalence of Peripheral Polyneuropathy Before and After Roux-en-Y Gastric Bypass and Sleeve Gastrectomy.
Article in Obesity surgery, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
purposePeripheral polyneuropathy (PPN) can occur in diabetes mellitus (DM), obesity, and after bariatric surgery (BS). We decided to evaluate PPN prevalence before (PreBS-PPN) and after BS (PostBS-PPN) and to look for variables that may be independently associated with both.
methodsIn this cross-sectional study, we evaluated 1467 participants with obesity and without DM before and 10.4 ± 6.8 months after Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG). The Michigan Neuropathy Screening Instrument and the International Physical Activity Questionnaire were used to define the presence of PPN and the Metabolic Equivalent Task (MET) spent per week, respectively. Using Poisson regression models with a robust estimator, the prevalence of PreBS-PPN and PostBS-PPN was analyzed as dependent variables.
resultsPrevalence of PostBS-PPN (10.5%) was lower than PreBS-PPN (20.4%, p < 0.001), with a prevalence of 12.7% post-RYGB and 8.4% post-SG (p = 0.072). In the univariate analysis, PreBS-PPN was associated with post-menopausal status (PMS), older age, and taller height. In twelve regression models, we found an independent association of PreBS-PPN with older age, PMS, and taller height. PostBS-PPN prevalence was associated with a higher fasting glycemia and stature, and a lower MET on univariate analysis, and with higher fasting glycemia, stature and RYGB in four multivariate regression models.
conclusionPPN occurs frequently in subjects with obesity without DM and is lower after BS. SG is not likely to be harmful in the development of neuropathy. Studies of PPN incidence and persistence after BS should clarify these factors.
