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

purposeQuality sleep is vital for good health. Although it is known that workhours affect sleep quality, it is not known at what point workhours begin to compromise sleep. Few studies consider workhours in the 'other job' (domestic and care work) or address reverse causality between sleep quality and how long people work. This study aimed to estimate the point at which weekly workhours harm sleep, among employed Australians aged 25-64.

methodsUsing Australian data (19,453 observations from 9,826 adults assessed 2013, 2017, and 2021), a maximum likelihood instrumental variable approach modelled the influence of domestic and care hours on workhours and then the effect of workhours on sleep. We tested for a non-linear pattern and a potential tipping point or limit at which sleep quality declines. Sleep quality scores were constructed from sleep duration (hours), quality rating, medications, and problems with onset.

resultsWe estimated a population tipping point of 42 workhours per week, beyond which sleep quality deteriorated. Notably, women demonstrated a lower tipping point (36 h) beyond which their sleep quality deteriorated compared to men (47 h), likely linked to their greater care and domestic workhours in the home.

conclusionsOur methods allowed us to specify the point at which weekly workhours were optimal for sleep quality and the point beyond which they become harmful. By considering unequal hours worked in care and domestic work, we were able to identify distinct gender differences in this relationship.
