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

backgroundMiscarriage and preterm delivery are the most important challenges of pregnancy. Different bacterial and viral infection may cause miscarriage and preterm delivery. Among bacterial factors, Mycoplasma genitalium and Chlamydia trachomatis have the most important role and human papilloma virus (HPV) is the leading viral factor in this regard.

methodsFirst void urine samples were collected from 119 pregnant women who visited health centers for routine first-trimester screening (12-14 weeks gestation). About 10 ml of the sample was centrifuged at 3000×g for 20 min and 1-2 ml of the sediment was transferred to sterile microfuges and stored at - 20 °C until analysis. DNA extraction was conducted using A101211 kits imported by Pars Tous Biotechnology Company. The following commercial kits, imported by Pars Tous Biotechnology, were used for PCR.

resultsThere is no significant association between urinary isolation of C. trachomatis and miscarriage (P = 0.93) and there is no significant association between urinary isolation of M. genitalium and miscarriage (P = 0.80). Regarding HPV, since all urine samples were PCR-negative, comparison was not possible. C. trachomatis was isolated from the urine samples of 6.72% of the pregnant women who underwent first-trimester screening in health centers using PCR. Previous studies reported a mean chlamydia isolation rate of 3% from urine specimens collected from pregnant women in general. T test showed no significant difference between the two groups (P = 0.10). Based on present study the mycoplasma isolation rate was 17.65% using PCR. Previous studies reported a mean mycoplasma isolation rate of 10% from urine specimens collected from pregnant women in general. T-test showed a significant difference between the two groups (P = 0.03). DISCUSSION: First void urine samples in pregnant women may be an appropriate sample for detection of C. trachomatis and M. genitalium; however, it is not a good method for HPV isolation therefore vaginal or cervical discharge specimens should be used instead for detection of HPV.
