Adenomyosis Subtypes and Endometrial Lesion Risk: A Propensity Score-Matched Study

685 patient records from a retrospective study conducted between January 2018 and December 2023 compare focal and diffuse adenomyosis subtypes. The data, shared by Xiaoxi Niu on figshare, shows a significantly higher incidence of endometrial lesions in the diffuse subtype group (49.5% vs. 35.6%) after matching 188 patient pairs. Conditional logistic regression results, including an adjusted odds ratio of 2.05, are included.

Use Cases

• Train classification models to predict endometrial lesion risk based on adenomyosis subtype and patient covariates.
• Conduct propensity score matching simulations for observational clinical studies using the described methodology.
• Perform subgroup analysis to investigate effect modifiers, such as age, on the association between adenomyosis and concurrent conditions.

Strengths

• Includes data from 685 patients with confirmed adenomyosis, providing a substantive sample size.
• Uses a 1:1 propensity score matching on 6 key baseline confounders to reduce selection bias.
• Contains specific statistical results, including an adjusted odds ratio of 2.05 with a 95% confidence interval.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for the final matched dataset is unknown, which may limit suitability assessment.
• Data may reflect temporal and institutional bias inherent to the single retrospective study design.
