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

BACKGROUND AND

objectiveAdequate control of blood pressure in younger females is of crucial importance, because they are at higher risk of hypertensive target organ damage compared with males of similar age. In addition, female sex is a risk factor for adverse effects of antihypertensive drugs, especially dihydropyridines. This study set out to assess the incidence of adverse reactions during dihydropyridine use in a real-life clinical setting, focusing on the influence of female sex and age.

methodsThe incidence of adverse reactions to dihydropyridine calcium channel blockers were investigated in 11,918 Japanese patients who participated in the Drug Event Monitoring project of the Japan Pharmaceutical Association conducted in Kumamoto prefecture. A multiple logistic regression analysis was used to determine the association between the incidence of adverse symptoms and female sex, with adjusted odds ratios (ORs) and 95% confidence intervals (95% CIs).

resultsVasodilation-related adverse symptoms occurred significantly more often in females than in males (OR 1.87, 95% CI 1.28-2.71, p=0.001). Furthermore, among females only, the younger age group (<50 years) complained of vasodilation-related symptoms more frequently (OR 2.39, 95% CI 1.02-5.59, p=0.045) and the older age group (≥80 years) complained of vasodilation-related symptoms less frequently (OR 0.56, 95% CI 0.33-0.95, p=0.030) than the middle age group (50-79 years).

conclusionTo the best of our knowledge, this is the first report showing that younger females are at high risk for vasodilation-related adverse symptoms during dihydropyridine use in a real-life clinical setting. These results should be verified in clinical studies using larger samples of young patients and more parameters.
