Effect of Nutri-jelly intake during radiotherapy on overall HRQOL. a–b Changes of HRQOL scores during RT in control group (a) and study group (b). Each bar represented mean quality of life score at different time of RT. Error bars indicated standard deviation (SD). One-way ANOVA test showed significant difference in control group (p < 0.0001) and no significant difference in study group (p = 0.8891). Bonferroni test identified time points with significant difference from baseline. c Comparison between study and control group. Each point represented mean quality of life score at different time of radiotherapy. Error bars indicated standard deviation (SD). Control group (radiotherapy only) (white square); study group (radiotherapy and one box of Nutri-jelly/day) (black square). Two-way ANOVA showed difference (p < 0.0001), followed by Bonferroni test. *p < 0.05; **p < 0.01; ***p < 0.001
