Air travel and incidence of pneumothorax in lymphangioleiomyomatosis

Table 1 Annual incidence rate of pneumothorax in LAM (n = 128)

Start of exposure period		Model 1	Model 2	Model 3
First symptoms of LAM		0.12 (0.1, 0.14)	0.18 (0.13, 0.24)	0.08 (0.05, 0.11)
LAM diagnosis		0.09 (0.07, 0.11)	0.11 (0.07, 0.15)	0.05 (0.03, 0.08)

Data were calculated from 3 models: Model 1: constant risk of PT across the whole LAM population, standard Poisson regression. Model 2: variable risk from one patient to another, negative binomial regression. Model 3: variable risk from one patient to another, Poisson regression with random intercept. Results are expressed as incidence per patient per year (95% confidence intervals)
