^*Fitted model: estimated microcirculatory parameters = ß₀ + ß₁^* gestational age at birth + ß₂^* days of life; ß₀: intercept-term.

^**Fitted multivariable adjusted model: estimated microcirculatory parameters = ß₀ + ß₁^* gestational age + ß₂^* days of life + ß₃^* mean arterial blood pressure + ß₄^* heart rate + ß₅^* oxygen saturation; ß₀: intercept-term.

⁺Statistically significant results are displayed in bold.
