Likelihood ratios for independent variables to predict uncontrolled asthma. Binary logistic regression data showing likelihood ratios (LR) with 95% confidence intervals (CI) for positive answers to the individual RCP questions and other independent variables to predict a uncontrolled asthma as defined by C-ACT/ACT or b reduced quality of life as defined by MiniPAQLQ score <6. “BTS step” refers to 2014 BTS treatment steps, separated into populations on step three or above or below three. BMI was categorised as <20 or ≥20. SABA: Short acting beta-2 agonist canisters prescribed to patient in the six months preceding the asthma review, categorised into those receiving more than two canisters and those receiving two or less
