Length of hospital stay (LOS)	60	7,056,550	348.80	− 0.325^ad

Positive effect at a small^a or medium^b size; ^cnegative small effect size; ^da negative effect size for hospitalization and the LOS variable favours the intervention group; ^ea single item from the 23-item version of the KCCQ; ^fcalculated as following: (physical limitation score + symptom frequency score)/2
