Failure to recover from proactive semantic interference predicts trajectory of decline in everyday function among older adults with amnestic mild cognitive impairment.
Article in International psychogeriatrics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectivesTo evaluate the predictive utility of proactive semantic interference (PSI) and failure to recover from proactive semantic interference (frPSI) deficits on the longitudinal everyday functional decline on the Clinical Dementia Rating Sum of Boxes (CDR-SOB) among older adults with amnestic mild cognitive impairment (aMCI).
designLongitudinal prospective cohort study.
setting1Florida Alzheimer's Disease Research Center (1FLADRC).
participants97 older adults aged 54 to 98 years who were diagnosed with aMCI following a baseline evaluation. The average age was 71.9 years, 51 % male, average education 15.7 years, and 56 % Hispanic. The mean MMSE score was 28.0. Participants were followed annually for 3 to 4 visits with a mean follow-up time of 38.9 months (range 22.7 to 70.3 months). MEASUREMENTS: CDR-SOB were obtained at each visit and the latent growth curve trajectory of CDR-SOB was estimated. The associations between PSI and frPSI and the growth curve trajectory of CDR-SOB were examined.
resultsThe growth curve model that best fits the CDR-SOB trajectory was a linear form and included the fixed and random effect of intercept and slope of time. After adjusting for age, sex, education, Hispanic background, Hopkins Verbal Learning Test (HVLT) immediate and delayed recall, and amyloid positivity, frPSI (β = -0.134, se=0.04, p < 0.01) remained statistically significant in predicting a steeper slope on the trajectory of decline in CDR-SOB.
conclusionsfrPSI at baseline predicted the rate of everyday functional decline over time among participants with aMCI regardless of amyloid status and demonstrated its utility of longitudinal prediction of change in CDR-SOB.
