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

Female infertility is a prevalent reproductive disorder with high genetic heterogeneity. Previous reports have demonstrated the causal role of biallelic pathogenic variants in the Subcortical Maternal Complex (SCMC) genes in female reproductive failure with some leading to infertility, early embryonic loss, and molar pregnancies, while others are compatible with live birth with and without multilocus imprinting disorders (MLID). Here, we report two deleterious protein-truncating variants, c.1326delG, p.Leu443Phefs*78 and c.2802_2803del, p.Arg935Metfs*15, in heterozygous state in the NLRP2 gene of a patient with primary infertility, four early miscarriages, and one failed attempt of intracytoplasmic sperm injection. We show that the two variants mediate mRNA decay in EBV-transformed lymphoblastoid cells from the patient, lead to decreased NLRP2 protein levels, and alter NLRP2 interactions with other members of the SCMC in vitro. This study emphasizes the importance of performing clinical exomes for patients with recurrent reproductive failure and reporting their variants and reproductive histories to improve patient counseling.
