Input: Consider Input: Question: Is eating disorder symptomatology associated with pregnancy and perinatal complications in a cohort of adolescents who were born preterm?
Answer: These results indicate that traumatic episodes early in life, including brain insults, do not appear to increase the susceptibility of developing eating disorder symptomatology, depression, deficiency of self-esteem, or distortion of body shape during late adolescence.

Output: no


Input: Consider Input: Question: Does intensity-modulated whole pelvic radiotherapy provide effective dosimetric outcomes for cervical cancer treatment with lower toxicities?
Answer: An intensity-modulated radiotherapy plan with appropriate margins encompassing the primary tumour and potential microscopic pelvic disease reduces the dose to organs at risk without compromising target coverage. Intensity-modulated radiotherapy is an appropriate definitive treatment for patients with cervical cancer.


Output: yes
