Clinical Anthropometry in Male Infertility: Differences Between Men With and Without Klinefelter Syndrome.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionKlinefelter syndrome (KS) is one of the most common genetic causes of male infertility and is frequently associated with characteristic anthropometric features. However, few studies have directly compared body proportions between patients with KS and infertile men without KS in clinical settings in Japan. Therefore, the present study investigated physical characteristics, particularly arm span, in infertile men with or without KS. PATIENTS AND
methodsThe present study included 30 infertile Japanese men with KS and 289 infertile men without KS who visited the outpatient clinic for male infertility at our institution between January 2004 and July 2025. Clinical data included age, height, weight, body mass index (BMI), and arm span.
resultsArm span was significantly longer in the KS group than in the non-KS group (p = 0.046). Height (p = 0.019) and weight (p = 0.017) were also significantly higher in the KS group, whereas BMI did not significantly differ between the groups.
conclusionInfertile Japanese men with KS had a significantly longer arm span than non-KS infertile men, consistent with eunuchoid body proportions. These results underscore the clinical value of incorporating a routine anthropometric assessment, particularly an arm span measurement, in the clinical evaluation of male infertility.
