IL7R and chronic obstructive pulmonary disease: Since the lower the sensitivity, the greater the ability of the GP model to designate a case without COPD-E as negative, we confirmed that lnc-IL7R (total sensitivity = 0.167, theta = 0.000, nugget = 0.001), and latitude (total sensitivity = 0.001, theta = 0.000) are factors of amelioration in the specified region (Table 2, Table 3 and Table 4).
