Postoperative hemoglobin concentration and blood hemoglobin levels in RFFFs

Scatter plot for postoperative hemoglobin concentration (AU) at 2-mm tissue depth and blood hemoglobin level in RFFFs; r and p-value corresponding to Spearman correlation coefficient (*p = 0.040 upon adjustment for ischemia duration (min), mean arterial blood pressure (mmHg) and administered catecholamine dose (µg/min per kg) in multiple linear regression analysis); abbreviations: [c] = concentration, AU = arbitrary units
