Trial report in BMC cardiovascular disorders, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. It is linked to trial NCT03081949 (Peripartum Cardiomyopathy in Nigeria), which is not on this map. Cited by 17 papers, 2 of them syntheses 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

backgroundWe studied the efficacy and safety of selenium supplementation in patients who had peripartum cardiomyopathy (PPCM) and selenium deficiency.

methodsWe randomly assigned 100 PPCM patients with left ventricular ejection fraction (LVEF) < 45% and selenium deficiency (< 70 μg/L) to receive either oral Selenium (L-selenomethionine) 200 μg/day for 3 months or nothing, in addition to recommended therapy, in an open-label randomised trial. The primary outcome was a composite of persistence of heart failure (HF) symptoms, unrecovered LV systolic function (LVEF < 55%) or death from any cause.

resultsOver a median of 19 months, the primary outcome occurred in 36 of 46 patients (78.3%) in the selenium group and in 43 of 54 patients (79.6%) in the control group (hazard ratio [HR] 0.69; 95% confidence interval [CI] 0.43-1.09; p = 0.113). Persistence of HF symptoms occurred in 18 patients (39.1%) in the selenium group and in 37 patients (68.5%) in the control group (HR 0.53; 95% CI 0.30-0.93; p = 0.006). LVEF < 55% occurred in 33 patients (71.7%) in the selenium group and in 38 patients (70.4%) in the control group (HR 0.91; 95% CI 0.57-1.45; p = 0.944). Death from any cause occurred in 3 patients (6.5%) in the selenium group and in 9 patients (16.7%) in the control group (HR 0.37; 95% CI 0.10-1.37; p = 0.137).

conclusionsIn this study, selenium supplementation did not reduce the risk of the primary outcome, but it significantly reduced HF symptoms, and there was a trend towards a reduction of all-cause mortality. CLINICAL
