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

backgroundSleep disorders are thought to be common in women with in vitro fertilization and embryo transfer (IVF-ET) conception. Although a few studies have investigated the association between maternal sleep quality and infant birth weight, it is unclear to what extent birth weight is associated with sleep quality during pregnancy among these women. Therefore, we conducted a cohort study to assess sleep quality among women receiving IVF-ET during the subsequent pregnancy and investigated the association of self-report sleep quality on infant birth weight.

methodsThis study was a prospective cohort study recruiting women who were to receive assisted reproductive technology (ART). Sleep quality was measured by the Pittsburgh Sleep Quality Index (PSQI) before oocyte retrieval and in the first trimester, second trimester, and third trimester during pregnancy. A generalized estimating equation (GEE) model was applied to evaluate the associations between sleep quality at specific times and infant birth weight. A general linear model was conducted to explore which component of the PSQI questionnaire was most associated with infant birth weight.

resultsBetween August 2016 and August 2020, a total of 1344 women who had singleton births with IVF conception were included in the analysis. PSQI scores in the first trimester were highest (4.59 ± 2.47) but had no significant relationship with birth weight. After accounting for potential influencing factors, we found that poor maternal sleep quality in the second trimester was significantly associated with small for gestational age (SGA) among female infants (OR = 3.03, 95% CI = 1.04 to 9.71, P = 0.044), while no association was observed between sleep quality and birth weight in male infants (OR = 1.64, 95% CI = 0.68 to 3.99, P = 0.271).

conclusionsThese findings suggest that the sleep quality of women with IVF pregnancies may influence fetal weight in a trimester- and sex-specific manner.
