P-values provided for dichotomous data were obtained using Fisher’s exact chi-squared tests. Odds ratios (OR) have been provided for work disabled relative to employed. Continuous data were tested using independent t-tests assuming unequal variances.
a Datawere missing for 2 dcSSc, and 2 lcSSc subjects;
b Data were missing for 2 dcSSc, and 4 lcSSc subjects.
