A 1-Year Weight Management Program for Difficult-to-Treat Asthma With Obesity: A Randomized Controlled Study.
Trial report in Chest, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis 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
backgroundObesity-associated asthma results in increased morbidity and mortality. We report 1-year asthma outcomes with a weight management regimen, the Counterweight-Plus Programme (CWP), compared with usual care (UC) in a single-center, randomized controlled trial in patients with difficult-to-treat asthma and obesity. RESEARCH QUESTION: Can use of the CWP result in improved asthma control and quality of life compared with UC at 1 year in patients with difficult-to-treat asthma and obesity? STUDY DESIGN AND
methodsAdults with difficult-to-treat asthma and BMI ≥ 30 kg/m
resultsOf 36 patients recruited, 29 attended visits at 52 weeks (13 CWP and 16 UC). The CWP resulted in greater weight change (median, -14 kg [interquartile range (IQR), -15 to -9 kg]) compared with UC (median, 2 kg [IQR, -7 to 8 kg]; P = .015) at 52 weeks. A greater proportion achieved MCID with the CWP vs UC in AQLQ (71% vs 6%, respectively; P < .001). No between-group differences were observed in ACQ-6. Median exacerbation frequency was reduced over 52 weeks with the CWP from 4 (IQR, 2 to 5) to 0 (IQR, 0 to 2) (P < .001), although no between-group difference was observed. Seventy percent of the CWP group lost ≥ 10% body weight and had improvement in ACQ-6 (mean difference, -1.1; 95% CI, -1.9 to -0.3; P = .018) and AQLQ (mean difference, 1.2; 95% CI, 0.4, 2.1; P = .011) across 52 weeks.
interpretationIn this study, the use of a dietitian-supported weight management program resulted in sustained weight loss and is a potential treatment for obesity in asthma. The CWP resulted in a higher proportion achieving MCID improvements in AQLQ compared with UC. Within-group differences in AQLQ and exacerbation frequency suggest potential with the CWP. These encouraging signals justify a larger sample study to further assess asthma-related outcomes.
