  • Significant differences between groups were detected by means of χ2 test for categorical variables, and by the Student's t-test or Mann-Whitney test for continuous variables, as appropriate. Univariate analysis of variance (ANCOVA), adjusted for age and gender, was used to compare hospital length of stay and in-hospital mortality between the two groups.

  • Significant p values are highlighted in bold.

  • CAP, community-acquired pneumonia; CAP-DM, DM in CAP; DM, diabetes mellitus.
