SD: standard deviation; CI: confidence interval.
*Adjusted for baseline (T0) values using generalized estimating equation (GEE)—population averaged model. 1i-, 2i-, and 3i-proportion of in-service nurses evaluated at T0, T1, and T2 were 28, 28, and 22, respectively. 1p-, 2p-, and 3p-proportion of preservice nurses evaluated at T0, T1, and T2 were 46, 46, and 43, respectively.
