The correlation between plasma cortisol levels and scores of psychological scales among patients with recurrent depressive disorder in Vietnam.
Article in PloS one, 2025. 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
objectivesWe aimed to examine levels of plasma cortisol in the morning and evening before and after standardised treatment, and analyze the correlation between these levels and scores of psychological assessment scales among patients with recurrent depressive disorder (PRDD) in Vietnam.
methodsFrom January 2020 to December 2021, a cross-sectional study was carried out at the National Institute of Mental Health in Bach Mai Hospital. After using a convenience sampling method, 109 consecutive patients met our criteria were recruited. We measured and analysed plasma cortisol levels in all participants at baseline (T0), two weeks after treatment (T1) and four weeks after treatment (T2). Spearman correlation was applied to assess the correlations between plasma cortisol at six different time and scores of six psychological assessment scales including HAM-D, HAM-A, BDI, SAS, DASS, and MMSE.
resultsAmong 109 PRDD, the percentage of subjects had high cortisol levels decreased during hospital treatment. At admission (T0), these figures were 4.76% in the morning and 8% in the evening. After 4-week treatment (T2), these figures declined to 1.32% and 3.09%, respectively. At T0, the morning cortisol concentrations had a positive correlation with the mean scores of HAM-A (r = 0.257), BDI (r = 0.251), and SAS (r = 0.276) (p ≤ 0.05), whereas the evening cortisol concentrations in the evening had a positive correlation with the mean scores of BDI (r = 0.197), SAS (r = 0.206), and Depression subscale of DASS (r = 0.252) (p ≤ 0.05). At T2, we did not detect any correlation between morning or evening cortisol levels and six test scores.
conclusionThe utilization of psychological measures for monitoring purposes can facilitate the assessment of alterations in cortisol levels among individuals experiencing recurrent depression, hence aiding in the treatment of depression in this population. Additional investigation using a more extensive sample size is required to furnish additional substantiation on this matter in Vietnam.
