Multivariate logistic regression model included the following variables (variable values in parentheses with reference group italicized): geography (from Asia, not from Asia), year of publication (≥2004, ≤2003), chemotherapy (received, did not receive), radiation therapy (received, did not receive)
Multivariate logistic regression model included the following variables (variable values in parentheses with reference group italicized): geography (from United States, not from United States), year of publication (≥2004, ≤2003), chemotherapy (received, did not receive), radiation therapy (received, did not receive). Similar point estimates and CIs obtained from models in which geography variable values were Asia versus Not from Asia and Europe versus Not from Europe
