1 · What the graph read from 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.

Abstract

objectiveThis study examined the effectiveness of behavioral weight management integrated with continuous glucose monitoring (CGM) among adults with overweight or obesity and type 2 diabetes.

methodsThis was a two-arm, parallel, randomized clinical trial. Participants (n = 151) were randomly assigned to intervention (INT; n = 75) or usual care (UC; N = 76). INT participants received a behavioral weight management program tailored for type 2 diabetes and CGM. UC participants received a session with a dietitian and educational materials. The primary outcome was 6-month change in HbA1c%. Additional outcomes included changes in weight, waist circumference, blood pressure, CGM metrics, diabetes stress, and treatment satisfaction.

resultsINT reduced HbA1c% (-0.87%; 95% CI: -1.17%, -0.57%) more than UC (-0.41%; -0.72%, -0.10%) (difference: -0.46%; -0.89%, -0.03%; p = 0.037). INT had greater reductions in percent body weight compared to UC (difference: -3.2%; -4.9%, -1.5%; p < 0.001). Several CGM metrics improved significantly more in INT than UC, and INT had significantly greater improvements in diabetes treatment satisfaction and regimen-related diabetes stress relative to UC.

conclusionsIntegrating CGM with a digital weight management program produced significantly greater improvements in HbA1c%, body weight, and other glucose metrics compared to UC among adults with overweight or obesity and type 2 diabetes.
