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

backgroundI/D polymorphisms of ACE are associated with the plasma ACE concentration. The ACE is associated with the angiogenesis of ovarian endothelium in vitro as well as steroidogenesis and follicular growth in cattle. Since ACE induces a high blood supply and hypersteroidogenesis in the ovary, it may be associated with polycystic ovary syndrome (PCOS) which exhibits hyperplasia, hypervascularity of the ovarian theca interna and stroma, as well as disorderd steroidogenesis. Therefore, we hypothesized that the ACE plays some roles in the human ovary. To investigate whether the ACE I/D polymorphisms are associated with the steroidogenesis disorder in PCOS and contribute to the susceptibility of PCOS in Chinese women, we designed a case-controlled association study in 582 individuals.

methodsThe ACE I/D polymorphisms were assessed in 582 reproductive-age women. Genotyping and frequency of ACE I/D polymorphisms were obtained by PCR amplification that was performed on genomic DNA isolated from blood leucocytes. Results were analyzed in respect to clinical test results.

resultsThe frequencies of the D allele and the genotypic distributions (DD, ID and II) in the women with PCOS did not differ from those in controls (P = 0.458). However, there were significant differences in the concentrations of testosterone among three genotypes both in the PCOS patients and controls (P = 0.0045, P = 0.0052, respectively). Differences were also found between these groups with distinct genotypes: DD versus II and DI versus II in the PCOS patients as well as DD versus DI and DD versus II in the controls. There were significant differences in the ratio of LH/FSH among three genotypes in the patients (P = 0.01). However, there were no statistical differences in the BMI, AAM, E2 concentrations and other serum hormone concentrations among the three genotypes both in the PCOS patients and controls.

conclusionThe ACE I/D polymorphisms were not associated with the pathogenesis of PCOS. However, the polymorphisms were associated with the steroidogenesis in the ovary. The observation indicated that the ACE I/D polymorphisms were not the key etiological factor, which in stead may be associated with the aggravated clinical manifestations of PCOS.
