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
Objective: This study aimed to investigate the potential categories of sleep quality in shift nurses using latent profile analysis, and to explore the characteristics and associated factors of sleep quality in each category. Methods: Convenience sampling was used to select 1,650 shift nurses from four tertiary A-level hospitals from May to June 2025. Data were collected using the Pittsburgh Sleep Quality Index (PSQI), the sleep chronotype questionnaire, the perceived stress scale, and a general demographic questionnaire. Latent profile analysis was conducted to determine the latent categories of sleep quality. Univariate and multinomial logistic regression analyses were used to investigate the associated factors of different sleep quality categories. A total of 1,650 questionnaires were distributed, of which 1,608 were valid, yielding a valid response rate of 97.5%. Results: The mean PSQI score among shift nurses was 7.23 ± 3.16 points, indicating overall sleep problems within this group. The sleep quality of night-shift nurses was categorized into four latent profiles: "good sleep quality" (44.4%), "moderate sleep quality" (40.7%), "sleep disorder-low sleeping pills" (9.6%), and "sleep disorder-high sleeping pills" (5.3%). A multivariate logistic regression analysis revealed that several factors were significantly associated with these sleep quality profiles. These factors included perceived stress, sleep chronotype, monthly night shifts, weekly working hours, age, and years of nursing experience, and marital status ( Conclusion: The sleep quality of shift-working nurses varies significantly. Nursing administrators should develop tailored management strategies and adopt targeted sleep interventions based on the identified patterns in nurses' sleep quality to improve their overall sleep quality.
