Long-term outcomes
T2 was small
For testing the relationship between observed SDM and long-term adverse outcomes (T3, 3 mo; T4, 6 mo), and the effect of oncologist training on long-term adverse outcomes, identical models were used as those used for analysis of the measurements shortly after the consultation T2, see Statistical analyses- Shared decision making and Statistical analyses- Intervention condition (oncologist training)). As for decisional uncertainty, no measurements at T3 nor T4 were available; this outcome variable was excluded from the models. To ensure sufficient statistical power at T3 and T4, analyses were performed only if the dropout percentage compared with T2 was small enough for imputation (<50%).
