  1. Interobserver agreement and correlation of the SPLASH-technique with the modified Goutallier Classification. The mean R for interobserver reliability was ρ =0.62. Correlation between the modified Goutallier Classification and the spectroscopic fat measurement with the SPLASH technique was ρ = 0.35. Correlation was measured using Spearman’s rank correlation test. (*p < 0.05) (**p < 0.01)
