Trial report in Journal of the American College of Cardiology, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT00006305 (Bypass Angioplasty Revascularization Investigation in Type 2 Diabetes), which is not on this map. Cited by 21 papers, 1 of them a synthesis that pooled it.

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

objectivesThe purpose of this analysis was to assess in patients with type 2 diabetes and stable coronary artery disease (CAD) whether the risk of all-cause mortality and cardiovascular events varied according to the presence or absence of angina and angina equivalent symptoms.

backgroundData on the prognostic value of symptoms in these patients are limited.

methodsPost-hoc analysis was performed in 2,364 patients with type 2 diabetes and documented CAD enrolled in the BARI 2D (Bypass Angioplasty Revascularization Investigation 2 Diabetes) trial to determine the occurrence of death and composite of death, myocardial infarction, and stroke during a 5-year follow-up according to cardiac symptoms at baseline.

resultsThere were 1,434 patients with angina (A), 506 with angina equivalents (E), and 424 with neither of these (N). The cumulative death rates (total 316) were 12% in A, 14% in E, and 10% in N (p = 0.3), and cardiovascular composite rates (total 548) were 24% in A, 24% in E, and 21% in N (p = 0.5). Compared with N, the hazard ratios adjusted for confounders were not different for death in A (1.11; 99% CI: 0.81 to 1.53) and E (1.17; 99% CI: 0.81 to 1.68) or for cardiovascular events in A (1.17; 99% CI: 0.92 to 1.50) and E (1.11; 99% CI: 0.84 to 1.48).

conclusionsWhatever their symptom status, patients with type 2 diabetes and stable CAD were at similar risk of cardiovascular events and death. These findings suggest that these patients may be similarly managed in terms of risk stratification and preventive therapies.
