Vascular endothelial growth factor levels in patients with obstructive sleep apnea: a meta-analysis.

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
Published articles regarding the blood levels of vascular endothelial growth factor (VEGF) in obstructive sleep apnea (OSA) patients are contradictory. The objective of this study was to explore whether VEGF levels is high or not in OSA subjects via quantitatively statistical analysis. The electronic databases of Pubmed, Web of Science, EMBASE were systematic searched. The VEGF levels and clinical characteristics of participants between OSA group and control group were extracted for analysis. Weighted mean difference (WMD) or standard mean difference (SMD) with 95 % confidence interval (CI) was calculated by fixed effects or random effects model. Appropriate statistical software was employed for data synthesis. Totaling 15 articles with 697 participants were included in this study. Pooled meta-analysis showed that blood VEGF concentrations were significantly higher in OSA patients than in control subjects (SMD 1.89, 95 % CI 0.92-2.87, p = 0.000). Subgroup analysis demonstrated that when compared with control group, OSA patients with age ≥50 years (SMD 2.54, 95 % CI 1.28-3.80, p = 0.000), apnea hypopnea index ≥30 events/h (SMD 2.47, 95 % CI 1.20-3.73, p = 0.000) had higher VEGF levels. Compared with control subjects, OSA patients had an elevated VEGF in serum (SMD 3.55, 95 % CI 1.82-5.28, p = 0.000) rather than in plasma. High blood VEGF concentrations were observed in OSA patients, particularly in the older and more serious patients.
