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.

2 · The registry

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

backgroundVery low levels of cardiac troponin T are associated with an increased risk of cardiovascular death in patients with stable chronic coronary disease. Whether high-sensitivity cardiac troponin T levels are associated with adverse cardiovascular outcomes in individuals without cardiovascular disease (CVD) has not been well studied. METHODS AND

resultsUsing 2 complementary study designs, we evaluated the relationship between baseline cardiac troponin and incident CVD events among diabetic and nondiabetic participants in the Women's Health Study (median follow-up, 12.3 years). All diabetic women with blood specimens were included in a cohort study (n=512 diabetic women, n=65 events), and nondiabetic women were sampled for inclusion in a case-cohort analysis (n=564 comprising the subcohort, n=479 events). High-sensitivity cardiac troponin T was detectable (≥ 0.003 μg/L) in 45.5% of diabetic women and 30.3% of nondiabetic women (P<0.0001). In models adjusted for traditional risk factors and hemoglobin A(1c), detectable high-sensitivity cardiac troponin T was associated with subsequent CVD (myocardial infarction, stroke, cardiovascular death) in diabetic women (adjusted hazard ratio, 1.79; 95% confidence interval, 1.04 to 3.07, P=0.036) but not nondiabetic women (adjusted hazard ratio, 1.13; 95% confidence interval, 0.82 to 1.55; P=0.46). Further adjustment for amino-terminal pro-B-type natriuretic peptide and estimated renal function did not substantially alter this relationship among diabetic women (hazard ratio, 1.76; 95% confidence interval, 1.00 to 3.08; P=0.0499), which appeared to be driven by a 3-fold increase in CVD death that was not observed in nondiabetic women.

conclusionsVery low but detectable levels of cardiac troponin T are associated with total CVD and CVD death in women with diabetes mellitus. Among healthy nondiabetic women, detectable compared with undetectable troponin was not associated with CVD events.
