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

backgroundChlamydia trachomatis is the etiology of most of sexually transmitted diseases. Colonization of C. trachomatis in the genital tract during early gestation has been associated with preterm birth, and preterm premature rupture of the membranes. The role of C. trachomatis on spontaneous abortion has not yet been proved completely. The aim of this study was to evaluate the frequency of C. trachomatis infection among pregnant women and its association with spontaneous abortion.

methodsThis case-control study was conducted from August 2012 until January 2013. Totally, 218 women were included; 109 women with spontaneous abortion with gestation age between 10-20 weeks (cases), and 109 women with normal pregnancy with gestation age between 20-30 weeks (controls) in Sanandaj, Iran. DNA was extracted from endocervical swabs and a PCR test was conducted for detection of C. trachomatis infection in women using specific primers. Independent T-test and Chi-square were used for comparison of quantitative and qualitative variables, respectively, and p<0.05 was considered significant.

resultsThe total prevalence of C. trachomatis infection was 38(17.43%) in endocervical swabs of women. However, the number of cases with C. trachomatis infections was 25 out of 109(22.9%) in the case group and 13 out of 109(11.9%) in control group, respectively. Association between chlamydia infection and spontaneous abortion was statistically significant (OR=2.198, CI 95%: 1.058-4.56).

conclusionOur study showed that C. trachomatis infection was associated with spontaneous abortion. Thus, screening and treatment of pregnant women may prevent this adverse pregnancy outcome.
