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

backgroundWhether additional benefit can be achieved with the use of statin treatment in patients with chronic heart failure (CHF) remains undetermined. HYPOTHESIS: Statin treatment may be effective in improving cardiac function and ameliorating ventricular remodeling in CHF patients.

methodsThe PubMed, MEDLINE, EMBASE, and EBM Reviews databases were searched for randomized controlled trials comparing statin treatment with nonstatin treatment in patients with CHF. Two reviews independently assessed studies and extracted data. Weighted mean differences (WMD) with 95% confidence intervals (CI) were calculated using random effects models.

resultsEleven trials with 590 patients were included. Pooled analysis showed that statin treatment was associated with a significant increase in left ventricular ejection fraction (WMD: 3.35%, 95% CI: 0.80 to 5.91%, P = 0.01). The beneficial effects of statin treatment were also demonstrated by the reduction of left ventricular end-diastolic diameter (WMD: -3.77 mm, 95% CI: -6.24 to -1.31 mm, P = 0.003), left ventricular end-systolic diameter (WMD: -3.57 mm, 95% CI: -6.37 to -0.76 mm, P = 0.01), B-type natriuretic peptide (WMD: -83.17 pg/mL, 95% CI: -121.29 to -45.05 pg/mL, P < 0.0001), and New York Heart Association functional class (WMD: -0.30, 95% CI: -0.37 to -0.23, P < 0.00001). Meta-regression showed a statistically significant association between left ventricular ejection fraction improvement and follow-up duration (P = 0.03).

conclusionsThe current cumulative evidence suggests that use of statin treatment in CHF patients may result in the improvement of cardiac function and clinical symptoms, as well as the amelioration of left ventricular remodeling.
