Effect of L-Citrulline Supplementation on Blood Pressure: a Systematic Review and Meta-Analysis of Clinical Trials.

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.
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
purpose of reviewSeveral interventional studies assessed the impact of dietary supplements on blood pressure. The aim of the present systematic review and meta-analysis was to determine the efficacy of L-citrulline supplementation on blood pressure. RECENT FINDING: Pubmed, Scopus, Google Scholar, and ISI Web of Science were comprehensively searched until May 2018 to assess whether L-citrulline reduces blood pressure. Human clinical trials which reported the effect of L-citrulline supplementation on aortic and brachial blood pressure were included. Characteristics of studies and potential sources of heterogeneity were tabulated. A subgroup analysis was performed to attenuate observed inter-study heterogeneity. A total of five interventions were found for meta-analysis. The impact of L-citrulline on brachial systolic (change 0.28 mmHg; 95% CI - 2.87, 2.31 mmHg) and diastolic (change - 1.56 mmHg; 95% CI - 4.32, 1.20 mmHg) blood pressure was not significant. Also, there was no changes in aortic systolic (change 0.22 mmHg; 95% CI - 4.81, 4.38 mmHg) and diastolic (change 0.26 mmHg; 95% CI - 2.27, 2.80 mmHg) blood pressure after L-citrulline supplementation. Participants' body weight status was a source of observed heterogeneity. The present systematic review and meta-analysis suggests that L-citrulline supplementation had no beneficial effect on blood pressure.
