Baseline comparison of oxyhemoglobin, deoxyhemoglobin, and O2 saturation parameters in SSc-RP patients and HC. Prior to the cold challenge, there were no statistically significant differences noted at baseline in oxyHb between SSc-RP and healthy controls (HCs) (A), but SSc-RP had greater levels of deoxyHb (B) and lower levels of O2 sat compared to HC (C) (p < 0.05). No significance (ns), *p < 0.05, **p < 0.01
