HRs of potential risk factors for events of serious infection (A), herpes zoster (B) and opportunistic infections excluding tuberculosis (C)—results from multivariable Cox regression models in the phases I–III and LTE studies *Medical history and/or complication of COPD. ^†In Unit=x, ‘x’ is the change in the continuous variable corresponding to which the change in hazards is observed. ^‡Based on exposure period before lymphopenia <500 cells/µL versus exposure period after lymphopenia <500 cells/µL. COPD, chronic obstructive pulmonary disease; HAQ-DI, Health Assessment Questionnaire-Disability Index; LA, Latin America; LTE, long-term extension.
