“ICC” refers to intraclass correlation, “C.I.” refers to confidence interval, “Sig.” refers to significance. Intraclass correlation coefficients are for absolute agreement using average measures and a two-way random effects model. Negative intraclass correlation coefficient for absolute agreement in such a small sample size will not be interpreted, this is represented by “N/A”. Significance considered at p ≤ 0.05. |
