Table 5 Predictors of ICS/LABA prescribing as determined by bivariate logistic regression according to lung function in 376 patients aged ≥40 years diagnosed with an obstructive lung disease in primary care according to whether COPD is indicated by spirometry (FEV 1 /FVC <0.7; n = 149) or not (n = 227)
