Risk of loco-regional progression estimated by pretreatment IBW status

Exposure	Loco-regional progression no/yes	Crude OR (95 % CI)	Adjusted OR (95 % CI)^a	Adjusted OR (95 % CI)^b
Pretreatment IBW status
≥90 % IBW (reference)	108/12	1.00	1.00	1.00
<90 % IBW	14/6	3.86 (1.25–11.91), p=0.02	2.08 (0.55–7.91), p=0.28	1.89 (0.49–7.25), p=0.36
