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

The polymorphisms of angiotensin-converting enzyme 2 (ACE2) gene have been suggested to be linked to increase risk of essential hypertension in multiple populations. However, the results are still debatable. To assess the association between ACE2 G8970A genetic polymorphism and essential hypertension, we conducted a meta-analysis of case-control studies across different ethnicity. PubMed, Embase, CBM, Wanfang and VIP databases were searched, and a total of 11 separate studies in females and nine separate studies in males met the inclusion criteria. Because ACE2 is on the X chromosome, data for each sex were analyzed separately. The selected studies contained 7,251 (4,472 females/2,779 males) hypertensive patients and 3,800 (2,161 females/1,639 males) normotensive controls. A statistically significant association was observed between the G8970A gene polymorphism and essential hypertension risk in female hypertensive group in the recessive genetic model (AA vs. GG+GA: P = 0.03, OR = 1.15, 95% CI = 1.02-1.30, P(heterogeneity) = 0.40, I(2) = 5%, fixed-effects model). Although no association was shown between the frequency of the A allele and the genetic susceptibility to essential hypertension in all male patients (A Allele: P = 0.38, OR = 1.10, 95% CI = 0.89-1.38, P(heterogeneity) = 0.02, I(2) = 56%, random-effects model), we found that the relationship between carrier of A allele and the essential hypertension risk in Han-Chinese male patients subgroup (A Allele: P = 0.006, OR = 1.21, 95% CI = 1.06–1.38, P(heterogeneity) = 0.10, I(2) = 44%, fixed-effects model). The current meta-analysis provided solid evidence suggesting that ACE2 gene polymorphism G8790A was probably a genetic risk factor for essential hypertension across different ethnic populations in female subjects and in Han-Chinese male subjects.
