Unspecified: age for 1 patient at Med-1.
Test for linear association uses continuous version of covariate, thus nDF of F test has 1 DF.
NOTE: According to univariate models (include 1 covariate) and 2 multivariable models, these characteristics are illustrated via mean Peer-RPAD scores and P values from F tests. The full multivariable model includes all covariates tabulated, and the reduced multivariable model includes covariates that were statistically significant at P ≤ .20 in either univariate or the full multivariable model according to F tests. Abbreviations: DF, degrees of freedom; nDF, numerator degrees of freedom; RPAD, Rochester Participatory Decision-Making Scale; SDM, shared decision making.
