Longitudinal Improvements in Health-Related Quality of Life Among Children Enrolled in the CANadian Paediatric Weight Management Registry (CANPWR) Over 3 Years.
Article in Pediatric obesity, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundHealth-related quality of life (HRQoL) can be impaired in children with obesity. Utilising data from the CANadian Paediatric Weight Management Registry (CANPWR), we examined changes in HRQoL up to 3-year after enrollment in paediatric weight management programs (PWMP) and demographic, socioeconomic, behavioural and health-related factors associated with it.
methodsData were collected from 2013 to 2020. Child (≥ 8 years) and parent-reported HRQoL data were assessed via questionnaire (PedsQL4.0) at baseline, 6-month, 1-, 2- and 3-year post-baseline in PWMP. Over time, HRQoL and associations with demographic, anthropometric, behavioural and health services data were examined using linear effects and mixed effects models.
findingsA total of 1145 participants were included at baseline (47.8% male; age 12.4 ± 3.3 years; BMI z-score: 3.5 ± 1.2; 68.8% White), 793 (69%) at 1- and 615 (54%) at 3-year post-baseline. Total HRQoL improved from baseline to 6-month and was higher at 3-year (child-total score: 69.9 ± 15.2 vs. 74.6 ± 14.5, p < 0.001; parent-total score: 64.6 ± 17.4 vs. 68.6 ± 17.0; p < 0.001). Total child-reported HRQoL was higher in boys (ß: 2.71, CI: 1.2-4.2; p < 0.01), children who identified as non-White (ß: 2.63, CI: 0.8-4.5; p < 0.01), and those with higher household incomes (ß: 3.65, CI: 1.6-5.7; p < 0.01), independent of BMI z-score. Higher total child-reported HRQoL scores were positively related to higher hours of clinic attendance (ß: 0.09 CI: 0.06-0.12; p < 0.01). In contrast, sleep disturbance, lower physical activity, and higher screen time were associated with lower total child-reported HRQoL independent of BMI z-score.
conclusionsBoth child- and parent-reported HRQoL scores improved over 3 years, and these changes were associated positively with clinic attendance and negatively with unhealthy behaviours.
