Cognitive recovery trajectories 3 months following stroke in Mexican American and non-Hispanic white adults.
Article in Journal of stroke and cerebrovascular diseases : the official journal of National Stroke Association, 2023. 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
objectivesWe examined whether cognitive trajectories from 0-3 months after stroke differ between Mexican Americans (MAs) and non-Hispanic white (NHW) adults. MATERIALS AND
methodsThe sample included 701 participants with ischemic stroke (62% MA; 38% NHW) from the population-based stroke surveillance study, the Brain Attack Surveillance in Corpus Christi (BASIC) Project, between 2008-2013. The outcome was the modified Mini Mental State Examination (3MSE, range 0-100 lower scores worse). Linear mixed effects models were utilized to examine the association between ethnicity and cognitive trajectories from 0-3 months following stroke, adjusting for confounders.
resultsMAs were younger, had lower educational attainment, and fewer had health insurance than NHWs (all p< 0.01). A smaller proportion of MAs were rated by informants as exhibiting pre-stroke cognitive decline than NHW (p < .0.05). After accounting for confounders, MAs demonstrated lower cognitive performance at post-stroke baseline and at 3-months following stroke (-2.00; 95% CI =-3.92, -0.07). Cognitive trajectories from 0-3 months following stroke were indicative of modest cognitive recovery (increase of 0.034/day, 95% CI =0.030-0.036) and did not differ between MAs and NHWs (p = 0.68).
conclusionWe found no evidence that cognitive trajectories in the first three months following stroke differed between MAs and NHWs. MAs demonstrated lower cognitive performance shortly after stroke and at three months following stroke compared to NHWs. Further research is needed to identify factors contributing to ethnic disparities in cognitive outcomes after stroke.
