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
backgroundPost-stroke depression (PSD) is a common neuropsychological complication that significantly impacts recovery and quality of life in stroke survivors. Understanding psychological factors such as uncertainty in illness and self-efficacy is crucial for developing targeted interventions and improving post-stroke outcomes. This study aimed to identify factors affecting PSD in stroke survivors, with particular focus on uncertainty in illness and self-efficacy.
methodsA cross-sectional study was conducted with 190 stroke survivors. PSD was assessed using the Korean version of the Geriatric Depression Scale Short Form (GDSSF-K), with scores > 5 indicating depression. Demographic and stroke-related characteristics, uncertainty in illness, and self-efficacy were evaluated. Chi-square tests, Fisher’s exact tests, independent t-test, and multiple logistic regression analysis controlling for demographic and clinical covariates were conducted to identify independent predictors.
resultsThe prevalence of PSD was 41.1% (n = 78). Significant associations were found between depressed and non-depressed groups in age (≥ 75 years), education level (elementary school or below), living arrangement (living alone), stroke recurrence, presence of hemiparesis, presence of dysphasia, and presence of pain. Participants with PSD demonstrated significantly higher uncertainty in illness (66.99 ± 9.88 vs. 57.87 ± 8.87) and lower self-efficacy (83.97 ± 19.12 vs. 98.03 ± 5.05). Multiple logistic regression analysis controlling for demographic and clinical covariates identified educational level (high school vs. ≥ bachelor: OR = 0.26, 95% CI: 0.07–0.94), stroke recurrence (OR = 6.91, 95% CI: 2.42–19.68), uncertainty in illness (OR = 1.08, 95% CI: 1.02–1.13), and self-efficacy (OR = 0.91, 95% CI: 0.85–0.97) as significant independent predictors of PSD, with the model explaining 54% of variance (Nagelkerke R²=0.536).
conclusionsPSD is prevalent among stroke survivors and associated with modifiable psychological factors. Educational level, stroke recurrence, uncertainty in illness, and self-efficacy were identified as significant predictors. These findings underscore the necessity for routine depression screening and comprehensive nursing care addressing both physical and psychological aspects of stroke recovery.
