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

backgroundKlinefelter Syndrome (KS) and Turner Syndrome (TS) are the two most common sex chromosome aneuploidies (SCAs). This study aims to investigate genotype-phenotype correlations of SCAs including classic, rare variants, and mosaic cases of KS and TS.

methodsTo understand the relationship between genotype and phenotype (i.e., clinical findings) in SCAs, retrospective cytogenetic and clinical data was collected for KS (n = 57) and TS (n = 92) cases from 2013 to 2022. The cohorts of KS and TS were divided into three subcategories (classic, mosaic, variant/other) based on the genotype.

resultsThe other supernumerary SCA (sSCA) group within the KS cohort had a significantly higher rate of developmental delay when compared to other KS groups. Although tall stature, pubertal delay, and congenital heart defects were described in the KS classic and other sSCA cohorts, these phenotypes were not seen in KS mosaics. Within the TS variant cohort, phenotype severity (i.e., number of accumulated pathologic clinical findings) was related to the complexity of the structural abnormality of X chromosomes.

conclusionOur study highlights that the SCA genotype (classic, mosaic, variant/other) modulates expression of the phenotype. Analysis of larger datasets may provide a deeper understanding leading to enhanced care management and improved patient outcomes.
