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

objectiveTo investigate the role of endothelial function, inflammatory markers, and N-terminal pro-brain natriuretic peptide (NT-proBNP) in patients with impaired chronotropic response during exercise test.

methods86 subjects were enrolled. Treadmill exercise test was conducted according to the modified Bruce protocols. Brachial ultrasound was used to measure endothelium dependent flow mediated vasodilatation (FMD). Chronotropic incompetence was defined as either failure to achieve 85% of the age predicted maximum heart rate or a low chronotropic index (< 0.8).

resultsOf the 86 patients, 20 (23%) exhibited chronotropic incompetence. The patients were divided into three groups according to chronotropic index: group 1, < 0.8 (n = 20); group 2, 0.8-1.0 (n = 26); and group 3, > 1.0 (n = 40). Patients with impaired chronotropic response had significantly lower FMD than those with higher chronotropic response (mean (SD) 2.8 (1.9)% v 5.0 (2.8)% v 5.3 (2.5)%, p = 0.002, for groups 1, 2, and 3, respectively). Serum concentrations of high-sensitivity C reactive protein (hsCRP), monocyte chemoattractant protein-1 (MCP-1), and NT-proBNP were significantly higher in group 1 than in groups 2 and 3 (hsCRP: 19 (12) v 9 (6) v 9 (6) mg/l, p < 0.05; MCP-1: 140 (51) v 133 (60) v 108 (46) pg/ml, p = 0.046; NT-proBNP: 4760 (1980) v 3710 (850) v 3910 (1060) mg/l, p = 0.019, respectively). In addition, chronotropic index was significantly related to FMD (r = 0.380, p = 0.001) and inversely related to hsCRP (r = -0.267, p = 0.013). By multivariate analysis, impaired chronotropic response was significantly related to endothelial dysfunction (p = 0.012).

conclusionPatients with impaired chronotropic response to graded exercise had endothelial dysfunction, enhanced systemic inflammation, and higher NT-proBNP concentrations. These findings may partly explain the mechanism of chronotropic incompetence as a predictor of cardiovascular risk and increased mortality.
