Meta-Analysis Data on Periodontitis, Tooth Loss, and Mild Cognitive Impairment Risk

A 538.1 KB document published on figshare in March 2026 contains the supplementary data for a systematic review and meta-analysis. The analysis, registered as PROSPERO CRD420251055491, pools results from five studies to investigate associations between periodontitis, tooth loss, and mild cognitive impairment (MCI). The author is Congcong Zou.

Use Cases

• Replicating the meta-analysis results based on the pooled odds ratios and confidence intervals.
• Conducting subgroup analyses based on diagnostic criteria for periodontitis mentioned in the description.
• Assessing heterogeneity in study results using the provided I² statistics.
• Investigating the relationship between severe periodontitis and cognitive function decline.

Strengths

• Includes fully-adjusted odds ratios (aORs) and 95% confidence intervals for primary associations.
• Provides specific heterogeneity metrics (I² values) for different analyses.
• Results are based on a systematic review of multiple databases up to March 2025.
• Data is openly available under a CC-BY-4.0 license.

Limitations

• The underlying dataset is a 538.1 KB DOCX file, which is a small supplementary document rather than a primary dataset.
• Row and column-level data are unavailable; the file likely contains summary statistics and textual results.
• The data's direct utility for machine learning is limited due to its aggregated, summary nature.
