Diabetes Mellitus and Post Stroke Cognitive Recovery After Ischaemic Stroke: A Study from Tertiary Care Centre in South India.
Article in Annals of neurosciences, 2026. 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
Background: Stroke is a leading cause of disability and mortality and is frequently associated with cognitive impairment. Diabetes mellitus is a common comorbidity in ischaemic stroke and is linked with poor neurological outcomes. However, longitudinal evidence comparing the burden of post-stroke cognitive impairment and cognitive recovery trajectories between patients with and without diabetes remains limited. Purpose: The present study compared the prevalence and severity of cognitive impairment in ischaemic stroke patients with and without diabetes mellitus at baseline and on day 90 post-stroke, and evaluated whether diabetes mellitus influences the trajectory of cognitive recovery over 90 days. Methods: In this longitudinal follow-up study, 401 ischaemic stroke patients (167 with diabetes mellitus and 234 without) underwent cognitive assessment using the Montreal Cognitive Assessment (MoCA) scale at baseline and at 90 days post-stroke. Between group comparisons (diabetes vs non-diabetes) were performed using appropriate parametric or non-parametric tests. Cognitive recovery trajectories were analysed using a linear mixed-effects model. Results: Patients with diabetes mellitus were significantly older ( Conclusion: Patients with diabetes demonstrated a greater burden of cognitive impairment at baseline and on day 90; however, cognitive improvement over 90 days was comparable regardless of diabetes status.
