Association between diastolic blood pressure and post-stroke cognitive impairment: a real-world retrospective cohort study.

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
backgroundPost-stroke cognitive impairment (PSCI) is a common complication after stroke, and blood pressure management is vital for stroke survivors. However, the association between diastolic blood pressure (DBP) during post-stroke rehabilitation and the risk of PSCI remains unclear. This study aims to evaluate this association in a real-world stroke cohort.
methodsA total of 508 consecutive stroke patients admitted between May 2022 and March 2024 were included in this study. Univariate and multivariate logistic regression analyses were conducted to identify risk factors for PSCI. Restricted cubic spline (RCS) analysis was performed to explore the association between DBP and PSCI. Logistic regression models were used to evaluate the risk of PSCI in different DBP groups. Subgroup analysis was employed to assess the effect of DBP across different subgroups.
resultsDuring a median follow-up of 5.5 months, 41% of patients were identified as having PSCI. Univariate and multivariate logistic regression analyses indicated that low DBP is an independent risk factor for PSCI (odds ratio [OR] = 0.960 by 1 mmHg, 95% confidence interval [CI] = 0.933-0.988,
conclusionDBP during post-stroke rehabilitation is associated with the incidence of PSCI in a non-linear manner. Specifically, a low DBP level during this period is an independent risk factor for PSCI. Maintaining a DBP above 80 mmHg during rehabilitation is beneficial for preventing PSCI.
