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

Objective: Premature ovarian insufficiency (POI) with short stature and mild intellectual disability can have diverse genetic etiologies. We aimed to decipher the genetic basis of this complex phenotype in a 26-year-old female with a karyotype lacking aneuploidy. Design and Methods: This is a case study integrated with comprehensive genetic analyses. After standard techniques (karyotyping, CNV-seq, WES) failed to yield a diagnosis, Oxford Nanopore long-read sequencing was employed to map chromosomal breakpoints at single-base resolution. X-inactivation (XCI) analysis was also performed. Results: Long-read sequencing refined the karyotype to 46,X,t(X; 3;8) (q25; q21p21; p21),t(17; 22)(q21.2; q13) and identified direct disruptions of TAFA5, LARS2, and MYLK. XCI analysis demonstrated highly skewed XCI (5.35%), indicating preferential inactivation of the structurally normal X chromosome. Conclusion: We propose that highly skewed XCI is the primary driver of the patient's POI and short stature, while the three disrupted genes may serve as modifying factors. This study underscores the value of long-read sequencing in resolving CCRs and the importance of XCI analysis in female patients with X-chromosome rearrangements.
