Means and standard deviations are reported for continuous variables and percentages and sample sizes are included for dichotomous variables. Reported CRP mean and standard deviation values are from untransformed variables. All associations between CRP and other variables use log10-transformed values. Associations of primary variable with other variables were tested with either lineara, Poissonb, or logisticc regression.
CRP=C-Reactive Protein; BMI = Body-mass index; SES= socioeconomic status. Sx = symptoms; Dx = diagnoses.
