Memory improvement in African Americans with amnestic mild cognitive impairment.
Article in International journal of geriatric psychiatry, 2019. 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
objectiveAmnestic mild cognitive impairment (aMCI) has an uncertain course. Valid methods to evaluate memory change will best identify predictors of course. This issue is especially relevant to older persons in minority groups, who may have encountered life course factors that adversely affect cognition. METHODS/
designGrowth curve mixture models were used to identify trajectories of memory test scores obtained every 6 months over 2 years in 221 African Americans with aMCI.
resultsParticipants sorted into two classes, with clinically and statistically significant differences in memory scores over time. Class 1 (n = 28 [14.7%]) had sustained improved scores. Class 2 (n = 162 [85.3%]) scores remained low, fluctuated, or declined. Class 1 had better baseline cognition and daily function than class 2.
conclusionsThe observed rate of improved memory is lower than reported reversion rates from aMCI to normal cognition. Evaluating trajectories of memory test scores rather than changes in categorical diagnoses of aMCI, which may depend on recalling (or not recalling) one or two words, may yield a more valid indicator of cognitive change. These approaches require further study in minority groups.
