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

purposePolymorphisms in the control region of mitochondrial DNA (mtDNA) can affect generation of reactive oxygen species and impact in the pathogenesis of endometriosis. This study investigated the association of mtDNA polymorphisms with endometriosis.

methodsPatients were divided in two groups: endometriosis (n = 90) and control (n = 92). Inclusion criteria were as follows: women between 18 and 50 years, with histological diagnosis and surgical staging of endometriosis (endometriosis group) or undergoing gynecological surgery for tubal ligation, leiomyoma, or ovarian cysts, with no evidence of endometriosis (control group). DNA extraction was performed from peripheral blood. Sanger sequencing of mtDNA control region was performed, and polymorphisms were determined comparing the sequences obtained with the Cambridge Reference Sequence.

resultsThe frequency of polymorphisms T16217C (14.4 and 5.4% of endometriosis and control group, respectively; p = 0.049) and G499A (13.3 vs. 4.3%; p = 0.038) was higher in the endometriosis group, while T146C (32.6 vs. 18.9%; p = 0.042) and 573.2C (5.6 vs. 29.3%; p < 0.001) were lower. No difference was observed in haplogroups between groups.

conclusionmtDNA polymorphisms T16217C and G499A were associated with endometriosis, while T416C and 573.2C were shown to be associated with an absence of disease.
