Primary Biliary Cirrhosis Patient Survival Data from Mayo Clinic, 1974-1984

418 patients with primary biliary cirrhosis from a Mayo Clinic study between 1974 and 1984, with data on survival, drug trial participation, and clinical measurements. The dataset was created by authors E. Dickson, P. Grambsch, T. Fleming, L. Fisher, and A. Langworthy. It includes 20 features per patient, such as lab results and disease stage, after preprocessing steps like imputation and one-hot encoding.

Use Cases

• Predicting patient survival time based on clinical measurements like bilirubin and albumin.
• Analyzing the effect of the drug D-penicillamine versus placebo on disease progression.
• Modeling the relationship between disease stage and clinical symptoms like ascites and edema.
• Studying correlations between demographic factors (age, sex) and laboratory results (cholesterol, platelets).

Strengths

• Data from a well-known clinical study at the Mayo Clinic with 418 patient records.
• Includes 20 detailed clinical and demographic features per patient, such as drug type, lab results, and disease stage.
• Preprocessing steps like missing value imputation and one-hot encoding are documented.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
• Data is from a specific study period (1974-1984) and institution, which may limit generalizability.
