A total of 949 NPC patients during 1990-1993 were serially recruited. Their ethnicity and residential area since childhood were compared to the census data in 1956. The 95% confidence interval of odds ratios for Hakkas to Fukienese in various counties were found to overlap within a range from 0.85 to 1.15 without showing statistically significant difference from unity . This result indicates that there is no extra ethnic risk between the two groups in Taiwan.#1394#en-USNPCHakkasFukieneseincidenceethnicityjournal article
