1 · What the graph read from it

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.

2 · The registry

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

The Davos Alzheimer's Collaborative (DAC) Egypt Cohort (DAC-Egypt) is a newly established longitudinal study of cognitive aging in a community-based convenience sample of older Egyptian adults. The cohort's purpose is to characterize trajectories of cognitive decline and dementia risk factors in an understudied population, filling a critical gap in aging research in the Middle East. Participants (n = 1,530) aged 55 and above were recruited via regionally diverse convenience sampling, with detailed baseline data collected on demographics, health status, lifestyle, and cognitive function. Cognitive assessments included both traditional neuropsychological testing and innovative digital tools (digital voice/speech & olfactory-sensory assessments) to enable comprehensive monitoring. Key preliminary findings indicated a high prevalence of chronic diseases and notable socioeconomic disparities in cognitive performance among older Egyptians. Blood samples were collected from 98% of participants, and dried blood spot (DBS) cards were obtained for 88% of participants to facilitate future biomarker and genetic research. This study seeks to enrich the scientific field of dementia and Alzheimer's disease and related disorders (ADRD) for early detection and intervention strategies for cognitive health in aging populations.
