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

purposeWe aimed to investigate the association between sleep disturbance and menstrual problems in female Chinese university students.

methodsA convenience sample of 1006 female university students participated in this study. Sleep duration, sleep quality, and insomnia symptoms were assessed by the Pittsburgh Sleep Quality Index and the Insomnia Severity Index. A structured questionnaire was used to assess participants' demographics and menstrual characteristics.

resultsThe prevalence rates of irregular menstrual cycle, heavy menstrual bleeding, menstrual flow length ≥ 7 days, period pain, and premenstrual syndrome were significantly higher in participants with sleep disturbance than those without sleep disturbance (all p < 0.05). After adjusting for potential confounding variables, poor sleep quality and insomnia symptoms were significantly associated with menstrual flow length ≥ 7 days (OR = 1.81, 95% CI = 1.23-2.68, OR = 1.67, 95% CI = 1.13-2.45), period pain (OR = 1.55, 95% CI = 1.02-2.35, OR = 1.56, 95% CI = 1.02-2.37), and premenstrual syndrome (OR = 1.71, 95% CI = 1.30-2.24, OR = 1.93, 95% CI = 1.46-2.56). In addition, poor sleep quality was significantly associated with heavy menstrual bleeding (OR = 1.75, 95% CI = 1.12-2.72), and insomnia symptoms were significantly associated with irregular menstrual cycle (OR = 1.36, 95% CI = 1.02-1.80). However, short sleep duration (≤ 6 h) was only associated with premenstrual syndrome.

conclusionOur results suggested that sleep disturbance is associated with menstrual problems among female university students. More attention should be paid to improving the sleep quality and insomnia symptoms in individuals with menstrual problems.
