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

purposeFew studies have yet examined sleep quality among puerperal women during the coronavirus disease 2019 (COVID-19) pandemic. This cross-sectional study aimed to compare the sleep quality of puerperal women before and during the COVID-19 pandemic in Lanzhou, China. The study exploreed the factors that affect sleep quality among puerperal women.

methodsThe study population comprised puerperal women who went to the obstetric department of the Gansu Provincial Maternity and Childcare Hospital on the 42nd day after childbirth. Sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI). Data were collected by doctors in the obstetric department before the COVID-19 pandemic (Oct.-Dec. 2019) and during the COVID-19 pandemic (Feb.-Apr. 2020) in China. Multiple linear regressions were used to examine the association between the sleep quality of puerperal women and COVID-19 and to identify factors that affect the total PSQI scores.

resultsIn 2019, 546 puerperal women were assessed compared with 655 who were assessed in 2020. Compared with before COVID-19, the total PSQI scores of puerperal women improved during the COVID-19 pandemic. In addition, the influencing factors of sleep quality among puerperal women were the pandemic itself, age, conception method, and postpartum depression (PPD).

conclusionsIn contrast with other studies, there was no evidence for worsening sleep quality of puerperal women during the COVID-19 pandemic in Lanzhou, China. Puerperal women who underwent assisted pregnancy or developed PPD were more likely to experience poor sleep quality.
