Coronavirus disease 2019 (COVID-19) pneumothorax in the ISARIC4C dataset. a) Histogram of incidence of pneumothoraces over time (absolute numbers, light grey females, dark grey males); line graph of pneumothorax incidence (percentage with 95% confidence interval). b) Incidence of pneumothorax by age, ventilatory support and pandemic wave. c) Incidence of pneumothorax by age, ventilatory support and steroid therapy: NIV: noninvasive respiratory support; IMV: invasive respiratory support. d) Demographics and risk factors for pneumothorax in non-critical care and critical care patients. Critical care patients include those admitted to an intensive care unit (ICU) or high dependency unit (HDU). Sample size for multivariable analysis was n=61 046 and 10 719 for non-critical care and critical care populations, respectively. e) Risk factors for death in non-critical care patients. f) Risk factors for death in critical care patients.
