有人认为不同时期测得的血压值的综合是一项比单次血压测量更为准确的危险指标,而大多数这样的研究最大期限只有4～5年,因此有必要去研究更长时期的血压综合值。自1960年起,作者对878例40～59岁的男性随机进行体检,每年测量血压一次,平均收缩压为1960～1970年期间的收缩压总和除以测量次数,预期收缩压通过1960～1970年期间的收缩压读数从直线回归方程中算出。对1960～1985年间卒中的发病率和死亡率资料也作记录,同时记录吸烟量并测定血清胆固醇浓度。在这878例
Some people think that the synthesis of blood pressure values measured in different periods is a more accurate indicator of risk than single blood pressure measurement, and most of the maximum duration of such studies is only 4 to 5 years, it is necessary to study longer-term blood pressure Comprehensive value. Since 1960, the authors randomized 878 men aged 40-59 years to medical examinations. Blood pressure was measured once a year. The average systolic blood pressure was the sum of the systolic blood pressures from 1960 to 1970 divided by the number of measurements. The systolic blood pressure was expected to be between 1960 and 1970 Systolic blood pressure readings were calculated from the linear regression equation. The incidence of stroke and mortality data were also recorded from 1960 to 1985, and the amount of smoking was recorded and the serum cholesterol concentration was measured. In this 878 cases
