Given a passage with a question and an answer to that question, classify if the answer actually answers the question into 'yes' or 'no'. Output 'yes' if the answer answers the question and output 'no' if the answer does not answer the question.

Question: Does global transcriptional analysis suggest Lasiodiplodia theobromae pathogenicity factors involved in modulation of grapevine defensive response?
Answer: L. theobromae transcriptome was established and validated. Its usefulness was demonstrated through the identification of genes expressed during the infection process. Our results support the hypothesis that heat stress facilitates fungal colonization, because of the fungus ability to use the phenylpropanoid precursors and SA, both compounds known to control host defense.
yes

Question: Is a high body mass index in esophageal cancer patients associated with adverse outcomes following esophagectomy?
Answer: A high BMI is not associated with increased overall morbidity following esophagectomy; moreover, it is associated with decreased incidence of chylothorax. The better overall survival in patients with high BMI compared with those with low BMI might be due to a relatively low pathological stage. A high BMI should therefore not be a relative contraindication for esophagectomy.
no

Question: Does the use of recombinant erythropoietin for the treatment of chemotherapy-induced anemia in patients with ovarian cancer affect progression-free or overall survival?
Answer: The current results indicated that there was no difference in cancer-related PFS or OS with use of ESA in this cohort of women treated for ovarian cancer.

no
