Sex Effect on Obesity Indices and Metabolic Outcomes in Patients with Obese Obstructive Sleep Apnea and Type 2 Diabetes After Laparoscopic Roux-en-Y Gastric Bypass Surgery: a Preliminary Study.
Article in Obesity surgery, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 papers, 2 of them syntheses that pooled it.
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
backgroundRoux-en-Y gastric bypass (RYGB) surgery is an effective therapy for obstructive sleep apnea (OSA). However, little attention has been paid to the treatment goals systematically stratified by sex. The objective of this study was to assess how sex differences affect obesity indices and metabolic outcomes after RYGB surgery.
methodsA sleep questionnaire was conducted and medical histories were taken. Full-night polysomnography (PSG), anthropometric variables, and blood samples were collected.
resultsThirty-five consecutive patients with OSA who underwent laparoscopic RYGB surgery were prospectively examined for at least 6 months were included in the study. Significant improvements (p < 0.01) in sleep parameters (except for micro-arousal), obesity indices, and metabolic outcomes [except low-density lipoprotein in men and high-density lipoprotein (HDL) in women] were obtained in men and women with OSA. Men had higher baseline triglyceride (TG) (p < 0.01) and lower HDL levels (p < 0.01) but a larger neck circumference (NC) (p = 0.03) at follow-up than did women. However, only TG in men improved more than in women (p = 0.02).
conclusionsSleep parameters, obesity indices, and metabolic outcomes after RYGB surgery were of similar magnitude in women and men with OSA. Alleviating sleep and obesity problems was correlated with metabolic outcomes in men and women.
