Input: Consider Input: Question: Does proper timing of adjuvant chemotherapy affect survival in patients with stage 2 and 3 gastric cancer?
Answer: There is insufficient evidence to suggest starting adjuvant chemotherapy within 4 weeks after surgery for patients with D2 resected stage 2 and 3 gastric cancer. However, delayed treatment of adjuvant chemotherapy after 8 weeks showed worse survival outcomes than early and intermediate treatment initiation, suggesting that adjuvant chemotherapy should be considered start within 8 weeks after radical resection.

Output: yes

Input: Consider Input: Question: Is time point important for effects of syngeneic bone marrow transplantation for type 1 diabetes in mice?
Answer: These results indicated that syn-BMT should be performed, when diabetes is neither too new-onset nor too late-stage. Tregs represent one mechanism for syn-BMT-induced restoration of immune tolerance in STZ-diabetic mice.

Output: yes

Input: Consider Input: Question: Does truncation in the tcdC region of the Clostridium difficile PathLoc of clinical isolates predict increased biological activity of Toxin B or Toxin A?
Answer: Our data do not support a direct role for alterations in the tcdC gene as a predictor of hyperproduction of Toxin A and B in NAP1-related strains.
Output: no
