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: Garlic extracts have been demonstrated to be effective supplements for reducing blood pressure in hypertensive subjects. However, contradictory observations on the efficacy of garlic extracts have been reported in different studies. Objectives: To explore the efficacy of garlic, this study aimed to perform a meta-analysis of previously published controlled placebo trials and drew firm conclusions. Methods: We searched online databases, including Scopus, PubMed, and Science Direct, to obtain relevant articles on the role of garlic in reducing blood pressure in patients with hypertension. The literature search, data extraction, and analysis were performed independently by two researchers. Comprehensive Meta-Analysis Software v4 was used for all the analyses. Results: Twelve reports, comprising 405 patients treated with garlic derivatives and 333 receiving placebo, were included in this investigation. The results of the meta-analysis revealed a significant decrease in systolic blood pressure (mean difference: -8.121, 95% confidence interval [CI]: -10.95 to -5.28, Conclusions: Garlic extracts significantly lower blood pressure and may be prescribed by clinicians for patients with hypertension.
