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

backgroundPoor sleep quality is common among university students. However, evidence on its prevalence and associated factors among nursing undergraduates in Sri Lankan state universities remains limited.

methodsA descriptive cross-sectional study was conducted among 412 nursing undergraduates selected through stratified random sampling. Data was collected using a validated, pre-tested online self-administered questionnaire, which included the Pittsburgh Sleep Quality Index (PSQI) and Perceived Stress Scale (PSS). Statistical analysis was performed using SPSS version 27. Chi-square tests and one-way ANOVA were applied, with p < 0.05 considered significant. For clarity, 95% confidence intervals were reported for prevalence estimates and group comparisons.

resultsThe prevalence of poor sleep quality (PSQI ≥ 5) was 84% (95% Confidence Interval). Significant associations were found between sleep quality and living place, diet, electronic device use, sleep hygiene practices, medical conditions, clinical rotation schedules, and academic stress. Most participants (65.8%) reported moderate stress levels. No significant associations were observed with credit hours, assignments, Grade Point Average (GPA), or study hours.

conclusionsPoor sleep quality is highly prevalent among nursing undergraduates in Sri Lanka and is influenced by stress, lifestyle factors, and health conditions. Interventions focused on sleep hygiene and stress reduction are recommended. CLINICAL TRIAL NUMBER: Not applicable.
