Clinical and biochemical parameters stratified for tertiles of delta serum FGF21 (Final – Basal) levels.

Data are expressed as mean±SD or as median (interquartil range). FGF21 was log-transformed before analysis. P values obtain from one-way ANOVA or Kruskall-Wallis tests as appropriate. NS = not significant. WC = waist circumference; BMI = body mass index; FFAs = free fatty acids; Epi = epinephrine; BPM = beats per minute; RHR = resting heart rest; MHR = maximum heart rate; METs = metabolic equivalents. SBP = systolic blood pressure; DBP = diastolic blood pressure. delta = Final – Basal levels. Resting = value obtained before each test. Max = maximum value obtained during each test. Mean = sum of values/number of tests.
