Muscle morphology in morbidly obese patients with NAFLD and lean controls.

NASH = non alcoholic steatohepatitis, T1F = type 1 fibers, Δ coefficient = variability coefficient, T2F = type 2 fibers, EMCL = extramyocellular lipids, EMCL = intramyocellular lipids, RRF = ragged red fibers presence, COX = presence of cytochrome oxidase negative fibers.P* = significance level in the comparison between controls and obese patients;P** = significance level in the comparison between NASH and non NASH.
