Comparison of body weight change between patients receiving 2D-RT and 3D-CRT

Body weight change	2D-RT	3D-CRT	p-valuea)
Absolute change (kg)	–1.0 ± 0.9 (-2.0 to 0.7)	–0.9 ± 1.2 (–3.6 to 0.7)	0.733
Relative change (%)	–1.6 ± 1.5 (–3.6 to 1.2)	–1.3 ± 1.8 (–4.7 to 1.4)	0.957

Values are presented as mean ± standard deviation (range).

2D-RT, two-dimensional radiotherapy; 3D-CRT, three-dimensional conformal radiotherapy; absolute change, body weight at completion of radiotherapy (RT) – body weight at pre-RT; relative change, [(body weight at completion of RT – body weight at pre-RT) / body weight at pre-RT] × 100.
