  1. Definition of abbreviations: NTM = non-Tuberculosis mycobacterial infection; NS = not significant, yr = years, min = minimum, max = maximum, ND = not done, A = Asian, AA = African American, C = Caucasian, H = Hispanic, S = Samoan; IS = immunosuppressant; Lym = lymphocyte; AS = active smoker; EX = ex-smoker; NS = never smoker. Statistical differences were assessed using the Wilcoxon rank sum test. The p values listed are for the comparison between sarcoidosis and PPD-. No significant difference was seen between sarcoidosis and NTM groups.
