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

Infertility has recently become a growing social and economic world problem. Genital mycoplasmas, such as Mycoplasma hominis and M. genitalium, are most frequently associated with several adverse effects on men’s fertility. The present study aimed to determine the prevalence of M. hominis and M. genitalium in the semen samples in thenortheast of Iran. During thiscross-sectional study from February to May, 2018, 100 semen samples were collected from 100 infertile men in Mashhad, Khorasan Razavi province, northeast of Iran. The presence of M. hominis and M. genitalium was detected by cultivation, polymerase chain reaction (PCR), and Multiplex PCR assays. The colony of mycoplasma was confirmed by Diene’s stain; moreover, arginine hydrolysis, glucose, and urea utilization were evaluated. The following semen indices were analyzed according to World Health Organization guidelines for semen analysis: color, volume, appearance, liquefaction, viscosity, concentration, pH, leukocyte concentration, progressive motility, morphological normality, motile sperm concentration, functional sperm concentration, sperm motility index, and functional sperm. The gene of 16SrRNA (GPO1& MGSO primers) was used as the target gene of the Mycoplasma genus in PCR assay. Multiplex-PCR was performed with a specific primer for conserved regions in the 16SrRNA gene for M. hominis (RNAH1& RNAH2 primers) and the 140-kDa Adhesion Protein Gene for M. genitalium (MG1 & MG2 primers).According to the results,9 (9%) samples were PCR-positive for Mycoplasma spp , while there were 7 (7%) cases isolated by cultivation. M. hominis was detected in 8 (8%) samples by Multiplex PCR, while there was no evidence for M. genitalium. The mean age scores of all infertile and infected men were obtained at 31 and 30 years, respectively. The study could not show any statistical correlation between mycoplasma infection and abnormal semen parameters. The heterogeneity of mycoplasma prevalence in the reports can be ascribed to differences in geographic areas, the sensitivity of the identification method, condition of the group (fertile/infertile), sample size, and operator proficiency. Various results have been reported in numerous studies conducted on the relationship between mycoplasma infection and abnormal semen parameters.
