Basal and insulin stimulated splanchnic plasma flow was not significantly different between the two groups (NASH: 722 (646–798) versus 817 (652–982) ml/min; simple steatosis: 690 (613–766) versus 803 (638–968) ml/min, mean (95% CI), basal versus clamp periods, respectively, P = 0.87 interaction (group x time (basal vs. clamp)), P = 0.70 group-effect, P = 0.09 time-effect (basal vs. clamp)), Mixed Model). The gene discussed is INS; the disease is metabolic dysfunction-associated steatohepatitis.
