説明

With the government agency's state and movement of production statistics and other such data, this study made on the transition of morbidity and mortality rate of tuberculosis will concentrated on:(1) Contemplation on assessments made mainly from analysis of regression lines of 21 countries including Japan: The mortality rate par 100, 000 population as the subordinate variable and the difference of 1900 subtracted from the calender year as the independent variable.(2) Contemplation on assessments made in uniform manner from 46 prefectures of Japan excluding Okinawa. The results are as follows:(a) In the period other than the time during the two world wars up to 1955, transition of mortality rate of each country has been found to be nearly in a straight line.(b) The regression line after 1955 has been found to be declining in relatively moderate angle than before. Therefore the regression line of each country is refracted at the point of 1955.(c) We have found the relation between the coefficient value and the constant value of every regression line plotted on an ordinary graph to be nearly in a straight line.(d) The regression line of 46 prefectures are nearly alike above results (a), (b) and (c).But these refracted points seem to be 1960.
