Note. SD = standard deviation; T1 = time point 1; T2 = time point 2; PTSD = posttraumatic stress disorder; CRP = C-reactive protein; HDL = high-density lipoprotein; BMI = body mass index. Missing observations: Current PTSD symptom severity (T2) (n=1), measured WBC counts (T1) (n=3), measured WBC counts (T2) (n=5), estimated CD4/CD8 (T1) (n=6), estimated C4/CD8 (T2) (n=6), CRP (T1) (n=5), CRP (T2) (n=6), MetS (T1) (n=1), MetS (T2) (n=2), systolic blood pressure (T2) (n=5), diastolic blood pressure (T2) (n=5), HDL cholesterol (T1) (n=7), HDL cholesterol (T2) (n=7), waist-to-hip ratio (T1) (n=6), waist-to-hip ratio (T2) (n=6), BMI (T2) (n=7), triglycerides (T1) (n=5), triglycerides (T2) (n=4), fasting glucose (T1) (n=4), fasting glucose (T2) (n=6), A1c (T1) (n=2).aCRP values reported above are raw values. logCRP values were used in reported analyses. bMetabolic syndrome (MetS) severity was determined using confirmatory factor analysis (CFA) of raw laboratory values and physiologic measurements. The lower order factors represented: (a) blood pressure (indicated by two diastolic and systolic readings), (b) lipids/obesity (indicated by waist-to-hip ratio, body mass index [BMI], high density lipoprotein, and triglycerides); and (c) blood sugars (indicated by fasting glucose and glycated hemoglobin A1c levels). These three factors were specified to load together (i.e., to be accounted by) a higher-order factor representing overall MetS severity. cBlood pressure, dlipids, and hsugar are reported above as raw values. Indicators of these variables were used for the MetS CFA.
