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

backgroundEuploid miscarriage may indicate underlying non-genetic factors in the couples. This study aimed to investigate the subsequent live birth rates in women with a prior euploid or aneuploid sporadic miscarriage (SM) in assisted reproductive technology (ART).

methodsThis retrospective study included 1,186 eligible women with a prior cytogenetically confirmed SM who underwent subsequent blastocyst transfer cycles. The pregnancy outcomes were compared by maternal age and the ploidy of the previous miscarriage.

resultsIn women aged < 35 years, the subsequent live birth rate (LBR) was comparable between euploid and aneuploid SM groups (55.2% vs. 60.2%; P = 0.194). However, among women aged 35–37 years, the LBR was significantly lower in those with a previous euploid SM than in those with a history of aneuploid SM (38.2% vs. 52.6%; P = 0.038). Among women ≥ 38 years, the euploid SM group also demonstrated a lower LBR (26.7% vs. 39.8%; P = 0.072). After adjusting for confounders, prior aneuploid SM was associated with significantly higher odds of live birth in the 35–37 years group (aOR 1.861; 95% CI 1.030–3.361; P = 0.040), and a similar trend was observed in the ≥ 38 years group (aOR 2.251; 95% CI 0.977–5.190; P = 0.057).

conclusionA single euploid SM might be associated with reduced live birth rate in their subsequent pregnancies for women aged ≥ 35 years. However, the pregnancy outcomes were comparable in women aged <35 years, regardless of the karyotype of products of conception.
