Correction of the equation of "Weight loss (ΔW)"

Posted by greengo123 on 16 Jul 2013 at 13:35 GMT

Weight loss (ΔW) is defined as the relative percent of weight changes between weight measurement before and after the radiation treatment, and an "Minus Sign" is omitted in the corresponding equation. The correct equation of Weight loss should be:

ΔW= (Wpre-RT-Wpost-RT)/Wpre-RT × 100%
