Fig 1. Baseline correlation analysis.

Correlations between asprosin concentrations in plasma and surrogate parameters for insulin resistance at baseline before the clamp study. (a) Trend towards a correlation between asprosin levels and basal insulin dose normalized to fat-free mass. (b) Correlation between asprosin levels and serum insulin concentrations. All patients had no sufficient endogenous insulin production, therefore, serum insulin concentrations represented injected basal insulin concentrations. Shown are Spearman Correlation Coefficients and p-values. Basal insulin dose is given in units per day. Insulin concentrations are given in milliunits per liter.
