Extended Data Figure 3. Observational Correlation of insulin sensitivity and clearance related traits in the RISC study.
Pairwise Spearman’s Rank correlation. Red shades denote positive correlation, blue shared denote negative correlation between trait pairs, legend along bottom of heatmap shows colour scale relative to rho value. X denotes no significant correlation (P > 0.05). Abbreviations denote: IFC_OGTT – IFC calculated using OGTT measures, ISI_OGTT – Modified Stumvoll ISI calculated using OGTT measures. M_I – M/I index of insulin sensitivity measured by clamp. InsC0c – insulin measured at 0min during clamp. InsO0c - insulin measured at 0min during OGTT. InsC120c – insulin measured at 120min during clamp. InsO120c - insulin measured at 120min during OGTT. InsC_20c – insulin measured at 20min before clamp. EGP_B -basal glucose production, EGP_SS - glucose production during clamp, GCR_B - basal glucose clearance, ml/min/kg lean body mass, GCR_SS - steady state glucose clearance, ml/min/kg lean body mass, icl_clamp - peripheral insulin clearance (1/min/m2), icl_OGTT - endogenous "pre-hepatic" clearance during the OGTT, hie_0 - hepatic insulin extraction during clamp, OGIS - oral glucose insulin sensitivity index (ml min-1 m-2). ISR5dr - insulin secretion 5 mM glucose, beta cell dose response (pmol min-1m-2). ISR0 basal insulin secretion (pmol min-1m-2). ISRtot - total insulin secretion (nmol m-2).
