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

aims/hypothesisThe aim of this study was to assess gender differences in mortality and morbidity during 13 follow-up years after 6 years of structured personal care in patients with type 2 diabetes mellitus.

methodsIn the Diabetes Care in General Practice (DCGP) multicentre, cluster-randomised, controlled trial (ClinicalTrials.gov registration no. NCT01074762), 1,381 patients newly diagnosed with type 2 diabetes were randomised to receive 6 years of either structured personal care or routine care. The intervention included regular follow-up, individualised goal setting and continuing medical education of general practitioners participating in the intervention. Patients were re-examined at the end of intervention. This observational analysis followed 970 patients for 13 years thereafter using national registries. Outcomes were all-cause mortality, incidence of diabetes-related death, any diabetes-related endpoint, myocardial infarction, stroke, peripheral vascular disease and microvascular disease.

resultsIn women, but not men, a lower HR for structured personal care vs routine care emerged for any diabetes-related endpoint (0.65, p = 0.004, adjusted; 73.4 vs 107.7 events per 1,000 patient-years), diabetes-related death (0.70, p = 0.031; 34.6 vs 45.7), all-cause mortality (0.74, p = 0.028; 55.5 vs 68.5) and stroke (0.59, p = 0.038; 15.6 vs 28.9). This effect was different between men and women for diabetes-related death (interaction p = 0.015) and all-cause mortality (interaction p = 0.005). CONCLUSIONS/

interpretationCompared with routine care, structured personal diabetes care reduced all-cause mortality and diabetes-related death in women but not in men. This gender difference was also observed for any diabetes-related outcome and stroke but was not statistically significant after extensive multivariate adjustment. These observational results from a post hoc analysis of a randomised controlled trial cannot be explained by intermediate outcomes like HbA1c alone, but involves complex social and cultural issues of gender. There is a need to rethink treatment schemes for both men and women to gain benefit from intensified treatment efforts.
