Subjective memory concerns and AD/ADRD plasma biomarker associations in HABS-HD.
Article in Alzheimer's & dementia (Amsterdam, Netherlands). The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
introductionWe examined relationships among subjective memory concerns (SMC), plasma biomarkers, and objective memory within racially/ethnically diverse older adults.
methodsParticipants included 1618 cognitively unimpaired older adults (681 Hispanic/Latino [H/L], 164 non-Hispanic Black [NHB], 773 non-Hispanic White [NHW]) from the Health and Aging Brain Study-Health Disparities. Associations among SMC, plasma biomarkers (phosphorylated tau 181 [p-tau181], amyloid beta 42/40 [Aβ42/40], neurofilament light chain [NfL], total tau [t-tau]), and objective memory were examined.
resultsHigher SMC was associated with higher plasma p-tau181 and NfL levels in NHW participants only. Higher depressive symptoms were associated with higher plasma p-tau181 in NHB participants only. Higher SMC related to lower objective memory for H/L and NHW participants. Plasma biomarkers had unique patterns of association with memory tests by racial/ethnic group. DISCUSSION: Different patterns of subjective memory, objective memory, and plasma biomarker associations within racial/ethnic groups suggests variability in the utility of SMC for early detection of Alzheimer's disease-related changes.
