Bold typeface denotes statistical significance.
Coefficient is adjusted mean difference in PF score at follow-up compared to referent, with positive coefficient indicating higher (better) PF score, complete data only, n=1124.
*p<0.05.
†Per unit PF score at baseline.
BMI, body mass index; GPwSI, general practitioner with a special interest, PF, physical functioning.
