Notes. Source: Data are from National Social Life, Health, and Aging Project. CRP = C-reactive protein. Significance tests for differences in proportions are Wilcoxon–Mann–Whitney for education, income quintile, and exercise and χ² for smoking.

^aSignificance tests for differences in means are two-tailed t tests.

^bincludes androgens and anabolic steroids, nasal steroids, and inhaled corticosteroids.

^cincludes ssri, tricyclic, phenylpiperazine, tetracyclic, ssnri, and other miscellaneous antidepressants.
