Association of Pneumonia Type and Respiratory Function in People with HIV

Sven J. Walderich's dataset contains pulmonary function test (PFT) and medical record data for 259 people with HIV (PWH) in San Francisco, CA. The data, last updated in April 2026, analyzes the association between the number of pneumonia episodes and declines in lung function metrics like FEV1, FVC, and DLCO.

Use Cases

• Modeling the stepwise decline in FEV1, FVC, and DLCO %predicted based on pneumonia count.
• Predicting odds of airflow obstruction (post-bronchodilator FEV1/FVC < LLN) for patients with multiple pneumonias.
• Analyzing the association between impaired DLco (DLco < LLN) and recurrent pneumonia episodes.
• Comparing pulmonary function outcomes between bacterial and Pneumocystis pneumonia types.

Strengths

• Includes data for 259 participants with detailed clinical and demographic covariates.
• Reports specific statistical associations, such as 5.53 higher odds of impaired DLco for those with ≥3 pneumonias.
• Contains participant breakdowns by pneumonia count: 39% had none, 20% had 1, 19% had 2, and 22% had ≥3.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data is limited to a single cohort from San Francisco, CA, which may affect generalizability.
