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

Background: Insomnia is a prevalent sleep disorder worldwide, yet data among healthcare professionals in Southeast Asia remain limited. Occupational stressors, rotating shifts, and high emotional demands may increase vulnerability to sleep disturbance in this population. Objective: To estimate the prevalence of insomnia among Vietnamese healthcare professionals and to identify associated nocturnal symptoms, daytime impairments, and clinical associated factors. Methods: We conducted a nationwide multi-region cross-sectional survey of 1655 healthcare professionals across Vietnam. Participants completed a structured questionnaire assessing insomnia symptoms, daytime consequences, comorbidities, and occupational factors. Insomnia was ascertained per ICSD-3 criteria for chronic insomnia, requiring (i) ≥ 1 nocturnal symptom (DIMS: difficulty initiating sleep, difficulty maintaining sleep, or early-morning awakening); (ii) ≥ 1 associated daytime impairment; (iii) symptom frequency ≥ 3 nights/week; and (iv) chronicity ≥ 3 months, despite adequate sleep opportunity. Severity was evaluated using the Insomnia Severity Index (ISI). Logistic regression models estimated odds ratios (ORs) and adjusted odds ratios (aORs) with 95% confidence intervals (CIs), adjusting for age, sex, occupation, marital status, and stimulant use. Results: The prevalence of insomnia was 24.2% (95% CI, 22.2-26.3), higher in women than men and increasing with age. The most common nocturnal symptoms were nocturnal awakenings (84.2%) and sleep-onset difficulty (57.2%), while daytime impairments included memory complaints (74.6%), mood disturbances (55.4%), and excessive daytime sleepiness (59.5%). In multivariable analysis, independent associated factors of insomnia included nocturnal awakenings (aOR 6.11), sleep-onset difficulty (aOR 2.89), mood disturbance (aOR 2.20), morning headache (aOR 2.18), and memory impairment (aOR 1.63). Stimulant consumption, particularly tea or coffee (aOR 2.10) and alcohol (aOR 1.98), was also independently associated. Conclusion: Approximately one in four Vietnamese healthcare professionals experience insomnia, characterized by substantial nocturnal fragmentation and daytime dysfunction. Given its potential implications for clinician well-being and patient safety, systematic screening and integrated occupational sleep-health interventions are warranted.
