Associations of chronotype and social jetlag with depressive symptoms in shift nurses: a cross-sectional study.
Article in BMC nursing, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveTo investigate the prevalence of chronotype, social jetlag and depressive symptoms in shift nurses, and to explore the relationship between chronotype, social jetlag and depressive symptoms.
methodsFrom October to November 2024, a total of 301 shift nurses from a tertiary-level hospital in Sichuan, China were selected as the investigation objects by purposeful sampling method, and the investigation was conducted using the Morning and Evening Questionaire 5 (MEQ-5), the Munich Chronotype Questionnaire (MCTQ), and the Patient Health Questionnaire-9 (PHQ-9). The influencing factors of depressive symptoms were analyzed by multiple linear regression.
resultsThe detection rate of depressive symptoms in shift nurses was 20.1%, the proportion of morning type, intermediate type and night type was 16.7%, 76.4% and 6.9%, respectively, and the proportion of high social jetlag was 49.7%. Factors such as age, alcohol consumption, exercise persistence, chronic disease, health status, the chronotype of intermediate type and night type were significantly associated with higher depressive symptoms scores among nurses (P < 0.05).
conclusionsIntermediate and evening chronotypes were associated with higher depressive symptoms. It is suggested that nursing managers use chronotype as a basis when formulating intervention plans for depressive symptoms in shift nurses, which could help reduce their severity.
