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

Brain-derived neurotrophic factor (BDNF) has been implicated in cardiovascular disease. However, the role of BDNF in coronary slow flow phenomenon (CSFP) remains unclear. This study explored the relationship between serum mature BDNF (mBDNF) levels and thrombolysis-in-myocardial-infarction frame count (TFC) as a measure of CSFP. Serum mBDNF was measured in 125 patients (mean age 60.2 years, 57% women) with suspected coronary artery disease before undergoing coronary angiography. Based on the corrected TFC, 77 patients were categorized as having CSFP and 48 normal coronary flow (NCF). The relationship of mTFC (mTFC) and CSFP with serum mBDNF was analysed using multivariable linear and logistic regression. mTFC ranged from 15.9 to 68.5 and mBDNF from 13.2 to 60.6 ng/mL. Serum mBDNF was inversely correlated with mTFC (Spearman rho - 0.327, P < 0.001) and reduced in CSFP (median 25.9 ng/mL IQR 20.6, 32.2 vs. 34.5 ng/mL IQR 27.4, 41.6, P < 0.001). Multivariable linear and logistic regression analyses indicated that log
