AGT and diabetes mellitus: As a result, univariate analysis showed underlying history of DM, CVD, serum AGT, and BALF AGT statistical significance, with an odds ratio (OR) of the underlying DM history of 3.45 (1.98–6.07, p-value < 0.001, 95% CI), underlying CVD history of 3.52 (1.76–7.33, p = value 0.001, 95% CI), serum AGT of 4.04 (2.34–7.80, p-value < 0.001, 95% CI), and BALF AGT of 7.07 (3.64–15.22, p-value < 0.001, 95% CI).
