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: Dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis and elevated cortisol levels are frequently observed in Alzheimer's disease (AD) patients. This study aimed to explore the potential use of saliva cortisol levels as an early marker for the initial clinical stages of AD and to investigate the correlation between saliva cortisol levels and behavioral symptoms in AD patients. Method: The sample included 81 participants of similar ages: AD patients (n=30), individuals with subjective memory loss (SML) (n=31), and a healthy control group (n=20). Saliva samples were collected at 08:00 and 16:00, and cortisol levels were compared across these groups. The Mini-Mental State Examination (MMSE), adjusted for educational level, was administered to all participants. The SML and healthy groups completed the Subjective Memory Complaints Questionnaire (SMCQ) and the Geriatric Depression Scale (GDS). Caregivers of AD patients were interviewed using the Neuropsychiatric Inventory (NPI) to assess the relationship between cortisol levels and behavioral symptoms in AD patients. Results: Evening cortisol levels in the AD group were significantly higher than those in the SML group (p<0.001). However, when examining salivary cortisol levels, no significant differences were detected between the SML group and the healthy controls. A negative correlation was found between salivary cortisol levels and MMSE scores in AD patients. Additionally, a positive correlation was observed between evening cortisol levels and several items in the NPI among AD patients. Conclusion: Although no significant changes in salivary cortisol levels were found in the SML group, which does not support its use as an early indicator of AD, the results suggest that the HPA axis may be a cause of behavioral problems, particularly in patients with severe AD.
