Impact of weight loss on cardiovascular function in adolescents and young adults with overweight/ obesity and intellectual and developmental disabilities.
Article in Disability and health journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02561754 (Weight Management for Adolescents With IDD), which is not on this 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.

Abstract
backgroundOverweight and obesity affect over 60% of adolescents and young adults with intellectual and developmental disabilities (IDD) and are associated with impairments in cardiovascular (CV) function.
objectiveThis study aims to evaluate the impact of weight loss on cardiac strain and other measures of CV function in adolescents and young adults with IDD and obesity, addressing a current literature gap.
methodsAdolescents and young adults with IDD and obesity entering a weight loss parent trial (NCT02561754) were voluntarily co-enrolled in this observational ancillary study (49 participants representing 45% of those enrolled in the parent trial). The ancillary study CV testing was performed at baseline and 6 months including echocardiograms optimized for strain, pulse wave velocity, and treadmill stress testing. Changes in CV parameters were compared to changes in body mass index (BMI). Statistical analyses included medians (interquartile range), Spearman correlation with bootstrapping, and regression modeling (adjusting for IDD diagnosis), p < 0.05 significant.
resultsThe ancillary study cohort consisted of 21 females (42%), 23 participants with Down syndrome (47%), and 26 with autism (53%); the mean age was 16.5 ± 2.4 years (range 13-21 years). Average weight loss through the parent trial intervention was 6.5% (BMI decreased 6.0%) over 6 months, with 9/49 (18%) losing >10% body weight. The decrease in BMI correlated with increases in left ventricular (LV) global longitudinal strain (p < 0.01), tricuspid annular plane systolic excursion (TAPSE) (p = 0.02), LV lateral E/e' (p = 0.007), LV global circumferential strain (p = 0.01), and LV end-diastolic strain rate (p = 0.005). Modest changes in LV global longitudinal strain (p < 0.001) and TAPSE (p = 0.003) remained significant on multivariant modeling.
conclusionsWeight loss in adolescents and young adults with IDD and overweight/obesity relates to improvements in certain parameters of ventricular function.
