a
Number of patients without a VTE.
b
Number of patients with a VTE, rounded in decimals because of imputation.
c
Logistic regression formula y = a + bx, y = −6.677015 + 0.3332203x, predicted risk calculated by exp(−6.677015 + 0.3332203*TRiP(cast) score)/1+ exp(−6.677015 + 0.3332203*TRiP(cast) score).
