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: To characterize a rare fetal complex chromosomal rearrangement (CCR) derived from a maternal balanced translocation using integrated G-banding and CNV-seq analysis. Methods: Integrated G-banding and CNV-seq enabled precise karyotypic determination in the fetus, with familial verification confirming its derivation. Results: Karyotype analysis confirmed that the pregnant woman was a carrier of a balanced translocation, 46,XX,t(10;13)(p15;q22), while her husband had a normal karyotype. Combined G-banding and CNV-seq analyses diagnosed the fetal karyotype as 47,U,t(10;13)(p15;q22)mat,+der(13)t(10;13)dmat, resulting from 3:1 meiotic segregation of the maternal balanced translocation. Conclusion: This case confirms the pivotal role of integrated G-banding and CNV-seq in diagnosing complex chromosomal rearrangements. For families with a high recurrence risk, PGT is a mandatory intervention to prevent subsequent adverse reproductive outcomes.
