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

objectiveFollicle-stimulating hormone and estradiol (E2) have been associated with sleep in midlife women, however, few studies have examined the association of other hormones or environmental chemical exposure such as phthalates, with self-reported sleep quality. We assessed the relationship of self-reported sleep with hormones and phthalates.

methodsIn total, 762 women (aged 45-54 y, 459 premenopausal, and 303 perimenopausal) from the Midlife Women's Health Study answered self-reported questions regarding the frequency of sleep disturbances, insomnia, and restless sleep. Serum E2, progesterone, testosterone, serum hormone binding globulin, free E2 index, free testosterone index, E2:progesterone, and E2:testosterone were measured. Summary measures of phthalate mixtures, including the phthalates from plastic sources (sumPLASTIC), personal care products (sumPCP), di-(2-ethyhexyl) phthalate (sumDEHP), anti-androgenic phthalates (sumAA), and all phthalate metabolites measured (sumALL), were calculated from urinary phthalate metabolites. Ordinal logistic regression was used to fit each outcome sleep measure with all hormones and summary phthalates.

resultsProgesterone and testosterone were significantly negatively associated with the frequency of sleep disturbances and insomnia. Free testosterone index was also negatively associated with insomnia frequency. E2:progesterone was positively associated with frequency of sleep disturbances and restless sleep in self-reported nonsmokers. SumPCP and sumALL were significantly negatively associated with frequency of sleep disturbances, insomnia, and restless sleep. SumDEHP and sumPLASTIC were negatively associated with insomnia frequency. Further, the direction of association between phthalates and sleep appears to be dependent on the quartile of phthalate exposure. All significant associations between phthalates and sleep were in self-reported nonsmokers or former smokers.

conclusionsOur study supports previous literature that hormones beyond follicle-stimulating hormone and E2 are associated with sleep disruptions in menopause. Further, we are among the first to show that phthalate exposure is associated with sleep disruptions in midlife women.
