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

Background: Having detrimental effects on the health-care system, infertility can be related to some risk factors, especially different kinds of viruses. Human endogenous retrovirus-k (HERV-K) env, gag, np9, and rec can be considered as one of these viral agents that are likely to cause male infertility, and we attempted to evaluate it. Materials and Methods: This case-control study was conducted on sperm samples of 96 participants in Imam Hossein Hospital, Tehran, Iran, from January 2020 to December 2021. After extracting the RNA form these samples, we evaluated the expression of HERV-K env, np9, rec, and gag using quantitative real-time polymerase chain reaction (qRT-PCR). Results: Our data revealed that HERV-K, rec, np9, and env in abnormal samples were higher than normal ones. However, the opposite trend was true for gag expression since a meaningful reduction can be observed in abnormal samples. Conclusions: The results of our study suggested that there is a plausible correlation between the expression level of this virus's genes and the progression of infertility. We proposed this marker as a promising biomarker to diagnose infertility. However, further studies are required to support these results.
