Cohort-Based Reference Percentiles for six BODY-Q Health-Related Quality of Life Scales after Metabolic and Bariatric Surgery.
Article in Obesity surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundPatient-reported outcome measures (PROMs) are essential in follow-up after metabolic and bariatric surgery (MBS), capturing health-related quality of life (HRQL). The BODY-Q includes HRQL scales relevant to patients undergoing MBS but cohort-based reference percentiles for postoperative interpretation are limited.
objectiveTo derive five-year cohort-based reference percentiles for six BODY-Q HRQL scales after MBS.
methodsPatients aged 18-65 with laparoscopic Roux-en-Y gastric bypass (LRYGB) or sleeve gastrectomy (LSG) at two Dutch centers (2017-2019) were included. HRQL was assessed preoperatively, at 4 months and annually to 5 years using six BODY-Q scales: body image, physical functioning, physical symptoms, and psychological, social and sexual well-being. BODY-Q scores were converted to a 0-100 scale and summarized at the 10th, 25th, 50th, 75th and 90th percentiles. Subgroups were surgery type, sex, age and BMI.
results391 patients were analyzed (85.9% female; mean BMI 42.8 ± 4.5 kg/m
conclusionThis study provides exploratory five-year cohort-based reference percentiles for six BODY-Q HRQL scales after MBS. These percentiles provide descriptive context for interpreting postoperative scores, but should not be considered definitive normative standards, clinical benchmarks or decision thresholds without external validation.
