Cumulative risk of death for LTOT 24 h/day (N = 539) versus 15–16 h/day (N = 1,231) in oxygen-dependent COPD.

<p>The hazard ratio was 0.98 (95% CI, 0.85 to 1.14); adjusted for baseline age, sex, oxygen dose, PaO₂ (air), PaCO₂ (air), FEV₁, WHO performance status, body mass index, treatment with oral glucocorticoids, and comorbid diagnoses including anxiety, renal failure and number of cardiovascular diagnoses.</p

PAsampling_data

This dataset contains data from presence-absence registrations on the permanent plots of the Swedish National Forest Inventory. On each plot, registrations are made for two subplots. The data file is separated into three parts: the first contain information about the first subplot, the second about the second subplot, and the third about the union of the two subplots. Descriptions of the variables are given inside the data file
