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

introductionIn SURPASS-SWITCH, switching from dulaglutide to tirzepatide resulted in greater improvements in glycemic control and body weight in adults with type 2 diabetes (T2D). This study aimed to investigate the efficacy and safety of switching from weekly dulaglutide to weekly tirzepatide in adults with T2D in prespecified baseline subgroups from SURPASS-SWITCH. RESEARCH DESIGN AND

methodsThis phase IV, randomized, open-label, active-controlled, parallel-group, multicenter, multinational trial included adults with hemoglobin A1c (HbA1c) ≥7.0% to ≤9.5%, on a stable dose of dulaglutide for at least 6 months, on a stable dose of 0-3 oral antihyperglycemic medications for at least 3 months, with stable body weight, and body mass index (BMI) ≥25 kg/m

resultsReductions in HbA1c and body weight at week 40 were significant and consistently greater with tirzepatide across all prespecified baseline subgroups. HbA1c reduction was greater in the subgroups with higher baseline HbA1c and low baseline BMI. Weight reduction was greater for participants in the non-Hispanic or non-Latino subgroup. The safety profile was similar across subgroups. Nausea and diarrhea were usually the most frequently reported treatment-emergent adverse events in each subgroup.

conclusionsIn this subgroup analysis of SURPASS-SWITCH, switching to tirzepatide from dulaglutide was generally well-tolerated and associated with significant and consistent improvements in HbA1c and weight reductions versus dulaglutide across all baseline subgroups evaluated. These results indicate that switching to tirzepatide may provide a clinical option across a range of baseline characteristics when treatment goals are not being met with dulaglutide. TRIAL REGISTRATION NUMBER: NCT05564039.
