【摘要】 本文对安徽省35县高血压(≥160/≥95mmHg)和临界高血压(140～160/90～95mmHg)现患率同食盐销售量/人、年进行了相关分析。结果发现等级相关系数分别为r_s=0.6080(p<0.01)和r_s=0.3310(p=0.05)。但是两个相关系数的差异并无显著意义(u=1.464,p<0.05)。更多还原

【Abstract】 An analyses was carried out on the relationship of the prevalence rate of hypertension (≥160/≥95mmHg)and critical hypertension(140-160/90-95mmHg) with the sales of table salt for each person/year from 35 counties in Anhui province.It was found that rank correlation coefficient r_s=0.6080(p<0.01)and r_s=0.3310(P=0.05) respectively. However, the differences between two correlation coefficient were not significant(U=1.464,P>0.05).更多还原
