Comparison of the frequency of EB-8m with that of f variant in endemic NPC isolates.

*The 63 isolates include 50 NPC cases of the present study and 13 reported NPC strains [45–49].†p-value was obtained from McNemar’s test.‡OR: odds ratio.§95% CI: 95% confidence interval.Comparison of the frequency of EB-8m with that of f variant in endemic NPC isolates.*本研究共纳入63株分离株，其中50株来源于本研究的鼻咽癌（Nasopharyngeal Carcinoma, NPC）病例，剩余13株为已报道的鼻咽癌菌株[45–49]。†p值通过麦克尼马尔（McNemar）检验计算得到。‡OR：比值比（Odds Ratio）。§95% CI：95%置信区间（95% Confidence Interval）。地方性鼻咽癌分离株中EB-8m与f变体的频率比较。
