Summary of stepwise model building

Model Effect ΔOBJF* P-value
BASE No covariates included
INTERMEDIATE TPMT mutations on FM3 −8.69 <0.005
FULL TPMT mutations on FM3 −12.85 <0.0005
BSA on CL6-TGNs
*

Change in OBJF in comparison to preceding model. A ΔOBJF ≥6.63 is statistically significant at P < 0.01 for 1 degree of freedom. TPMT, thiopurine methyltransferase; BSA, body surface area.
