Clinical impact of parental consanguineous marriage in idiopathic nonobstructive azoospermia.
Article in F&S reports, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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
objectiveTo determine the frequency of parental consanguineous marriages (PCMs) in men with diagnosed idiopathic nonobstructive azoospermia (INOA) and to compare clinical and pathological parameters between azoospermic men with and without PCM.
designRetrospective.
settingA private clinic. PATIENTS: Two hundred forty-six men with INOA. Patients were divided into two groups: group 1 with PCM and group 2 without PCM. Clinical parameters, surgical sperm retrieval rates, and pathological findings were compared between the groups.
interventionsSurgical sperm retrieval.
main outcome measuresPCM and clinical parameters.
resultsAmong the 246 patients with INOA, 81 had PCM. Men with PCM had lower follicle-stimulating hormone (13.7 vs. 21.9 mIU/mL), higher testosterone (3.8 vs. 3.4 ng/mL), and larger testes (14.1 vs. 11.8 mL). In parallel with the clinical findings, the most common pathological pattern in men with PCM was maturation arrest. However, there was no difference in surgical sperm retrieval rate between men with (23.4%) and without (32.1%) PCM.
conclusionsOur data showed that PCM was present for 33% of men with INOA. The clinical parameters of men with PCM and INOA were significantly different than those without PCM, primarily demonstrating maturation arrest in testicular pathology. Further genetic research in families who have infertile male siblings may elucidate underlying rare genetic abnormalities in spermatogenesis.
