Data Sheet 1_Impact of hypertension history and blood pressure parameters on cognitive imp

20 observational studies involving 998,622 atrial fibrillation patients were included in this systematic review and meta-analysis. The study, authored by Xingxing Mi and published on figshare in 2026, evaluates associations between hypertension history, blood pressure parameters, and cognitive impairment risk. It reports pooled odds ratios and hazard ratios from meta-analyses performed using RevMan 5.4.

Use Cases

• Estimating the association between hypertension history and cognitive impairment risk based on reported odds ratios (OR: 2.22).
• Analyzing the impact of high-normal blood pressure levels (130-139/85-89 mmHg) on cognitive impairment based on reported hazard ratios (HR: 1.07).
• Investigating differential risks for mild cognitive impairment versus dementia based on subgroup meta-analysis results.
• Assessing study quality and heterogeneity in observational research using the NOS and AHRQ tools described in the methods.

Strengths

• Analysis is based on a large pooled sample of 998,622 patients from 20 studies.
• Includes specific, quantified risk estimates such as an odds ratio of 2.22 for hypertension history and a hazard ratio of 1.07 for high-normal blood pressure.
• Employs systematic review methodology with searches across eight databases and uses established quality assessment tools (NOS, AHRQ).

Limitations

• The dataset is a 17.2 KB DOCX document containing a research manuscript, not a primary data table; row and column structures are unknown.
• Column-level documentation is absent; field semantics must be inferred from the manuscript text after download.
• Data may reflect publication or selection bias inherent to the included observational studies.
