The pooled estimates for COPD-PS were as follows sensitivity of 0.66 (95% CI 0.47-0.63), specificity of 0.86 (95% CI 0.84-0.89), positive likelihood ratio of 3.00 (95% CI 1.65-5.47), negative likelihood ratio of 0.43 (95% CI 0.35-0.52) and diagnostic odds ratio of 7.24 (95% CI 3.91-13.4. The AUC of the summary ROC curve was 0.78. COPD-PS appears to be a useful tool for screening individuals with a high risk of COPD and guiding the selection of individuals for subsequent spirometry examination.KEY MESSAGESCOPD-PS is a simple and useful method
