Study on the association between night shift work and reproductive functions among male workers: a systematic review and meta-analysis.

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.
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
backgroundThere has been growing interest to study impact of night shift work on male reproductive health, which is regulated by the hypothalamic-pituitary-gonadal axis and influenced by circadian rhythms. This systematic review and meta-analysis aim to explore the association between night shift work and male reproductive health outcomes.
methodsThis systematic review and meta-analysis followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines (PROSPERO: CRD42022379770). Studies comparing male reproductive parameters [e.g., semen profile, testosterone, follicle stimulating hormone (FSH), luteinizing hormone (LH)] between night shift workers and non-shift workers were systematically searched in PubMed, Scopus and EMBASE databases. Heterogeneity (I
resultsEight studies were included in this review from 6397 citations screened. The pooled mean difference in sperm count was -18.38 × 10
conclusionThe analysis highlights the potential impact of night shift work on sperm parameters and hormone levels. Future research with standardized methods and larger samples is needed to better understand the circadian disruption's effects, informing healthcare practices and policies for male reproductive health.
