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

The importance of the central nervous system in cardiovascular events has been recognized. Recently, brain-derived neurotrophic factor (BDNF), a member of the neurotrophic factor family, is involved in depression mechanisms and also in stress and anxiety. Because BDNF is reported about cardioprotective role, we elucidated whether BDNF is associated with cardiovascular events in patients with chronic heart failure (CHF). We examined serum BDNF levels in 134 patients with CHF and 23 control subjects. The patients were followed to register cardiac events for a median of 426 days. BDNF was significantly lower in CHF patients than in control subjects (25.8 ± 8.4 vs 14.7 ± 8.4, P < 0.0001). Serum BDNF was also lower in patients with cardiac events than in event-free patients (16.1 ± 8.0 vs 12.5 ± 8.5, P < 0.0001). The cutoff value of BDNF was determined by performing receiver operating characteristic curve analysis. Kaplan-Meier analysis demonstrated that patients with low levels of BDNF experienced higher rates of cardiac events than those with high levels of BDNF. Multivariate Cox hazard analysis demonstrated that low BDNF levels (≤12.4 ng/mL) were an independent prognostic factor for cardiac events (hazard ratio 2.932, 95 % confidence interval 1.622-5.301; P = 0.0004). Adding levels of BDNF to the model with BNP levels, age, and eGFR for the prediction of cardiac events yielded significant net reclassification improvement of 0.429 (P < 0.001) and an integrated discrimination improvement of 0.101 (P < 0.001). Low serum BDNF levels were found in patients with CHF, and these levels were found to be independently associated with an increased risk of cardiac events.
