Forest plot assessing the effect of penehyclidine inhalation versus placebo inhalation in predefined subgroups. Logistic models were applied for assessment of treatment-by-covariate interactions. Treatment-by-covariate interactions were assessed separately for each subgroup factor, including age, sex, body mass index, respiratory disease, respiratory symptoms in the last month, preoperative cigarette smoking, type of anesthesia, location of surgery, and type of surgery.
