Demographics Of the 369 respondents, 199 were medical students and 170 were nonYmedical students, most aging from 15 to 25 years old. Of the surveyedmedical and nonYmedical students, 43.22% and 74.71%weremen, 56.78% and 25.29% were women, 5.53% and 10.00% were Buddhist, 1.51% and 2.94% were Christian, 3.01% and 2.35% were Muslim, 4.02% and 7.65% identified as ‘‘other,’’ and 85.93% and 77.06% were nonreligious, respectively. Other sociodemographic data of the respondents were concluded in SDC, Table S1, http://links.lww.com/TP/A977. Knowledge About Cadaveric Organ Donation Regarding awareness of the usage, regulations, and sources of cadaveric organs, 4.02% of medical students stated that they had detailed knowledge, 60.80% had some knowledge, and 35.18% had no knowledge. Among nonYmedical students, the percentages were 2.94%, 40.59%, and 56.47%, respectively. Compared with nonYmedical students, medical students had a better knowledge about cadaveric organ donation, such as its usage, regulations, and sources (PG0.001) (Table 1). With respect to the awareness of brain death and its diagnostic criteria, 67.84% medical students believed brain death to be irreversible, 10.55% believed reversible, and 21.61% were not sure, comparing with 54.71%, 11.76%, and 33.53% for nonYmedical students, respectively. Although 10.05% of medical students stated that they knew the diagnostic criteria of brain death in detail, 68.84% had some information, and 21.11% had no information comparing with 2.94%, 31.18%, and 65.88% for nonYmedical students, respectively. Thus, medical students were more likely than their nonYmedical student peers to have knowledge about brain death (P=0.024) and its diagnostic criteria (PG0.001) (Table 1). Regarding the appropriate time to conduct cadaveric organ donation, 71.86% of medical students and 58.82% of nonYmedical students identified brain death as the proper time, whereas 28.14% of medical students and 41.18% of nonYmedical students believed the appropriate time to be at heart death. The difference was of statistical significance (P=0.008) (
