Chemotherapy and Persistent Depression in Older Mexican Cancer Survivors: Secondary Analysis of the Mexican Health and Aging Study.
Observational study in Cancer investigation, 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
introductionDepressive symptoms (DS) are prevalent among cancer survivors and may be exacerbated by chemotherapy. However, longitudinal data on this relationship within the Mexican population are lacking. The current study aimed to analyze the relationship between chemotherapy and the persistence of depressive symptoms over time in cancer survivors.
methodsRetrospective observational study using Mexican Study of Health and Aging (MHAS) data (2012-2021). Participants aged 50+ included chemotherapy patients (n = 30) and healthy controls (n = 6,970). Depressive symptoms were assessed with a modified Center for Epidemiologic Studies Depression Scale. Mann-Whitney U, X
resultsChemotherapy recipients showed significantly higher depressive symptoms at early follow-ups (2012, 2015, 2018; p < 0.05), with no significant difference by 2021. Adjusted analyses indicated chemotherapy was associated with a more than twofold increase in odds of depression (OR = 2.165; 95% CI: 1.220-3.810). Lower education and comorbidities such as diabetes and hypertension were also independently linked to increased depression risk.
conclusionsChemotherapy is a significant predictor of persistent depressive symptoms among Mexican cancer survivors aged 50 and above. These findings highlight the critical need for integrated mental health screening and targeted psychosocial care within oncology settings.
