Associations of fruit and vegetable intake with sleep quality and stress among Hong Kong female nurses with different working status: a cross-sectional study.

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.
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
backgroundThe relationships of fruit and vegetable (FV) intake with sleep quality and stress among nurses with different working status are largely unknown. This study aimed to assess the FV intake among Hong Kong female nurses with varying working status and evaluate its associations with sleep quality and stress levels.
methodsA cross-sectional survey named "Hong Kong Women's Health Study" was conducted between 2019 and 2020. Systematic sampling was adopted to recruit eligible nurses from a local Nurses Association. Email invitations followed by mailed questionnaires were used for data collection. FV servings consumed every day with detailed descriptions. The Chinese version of the Pittsburgh Sleep Quality Index and Perceived Stress Scale-14 items were employed to evaluate sleep quality and stress level, respectively. Nurses' work status was classified as employed/retired and day work/shift work. Multivariate linear regression was applied.
resultsA total of 1,270 female nurses were included in the data analysis. The average FV intake was 2.91 servings/day, 88.7% of the participants consumed less than 5 servings/day. Nurses who were aged 45 and above, obese (BMI ≥ 25 kg/m
conclusionIncreased FV intake was associated with better sleep quality and lower stress levels among Hong Kong female nurses. The FV intake-stress relationship was strengthened in employed nurses and those working routine day shifts. CLINICAL TRIAL NUMBER: Not applicable.
