Subjective memory complaints of patients and caregivers and their association with sociodemographic and clinical factors in patients with neurocognitive disorders from Colombia.
Article in Research square, 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
Subjective memory complaints (SMC) are common in older adults and may signal cognitive decline. We examined the clinical correlates of patient-reported SMC and caregiver-reported complaints (CMC) and introduced their discrepancy (SMCΔ) as a potential marker of anosognosia or caregiver overestimation. We carried out a cross-sectional study and systematically assessed cognitive, functional, and behavioral domains of 6,708 individuals from a Latin American memory clinic. CMC scores were significantly higher than SMC and were more strongly associated with cognitive and functional impairments, while SMC was linked to neurological comorbidities and higher education. Psychiatric symptoms were associated with both CMC and SMCΔ. Lower cognitive scores predicted greater CMC, and SMCΔ was best explained by education, MoCA, and NPI-Q. Our findings suggest that SMC, CMC, and their discrepancy capture distinct aspects of disease awareness and caregiver perception, supporting the clinical utility of SMCΔ in early detection and assessment of neurodegenerative conditions.
