TABLE XXXVIII
No. examined. | Ht. Disease with history of Rh. fever. | Ht. disease without history of Rh. fever. | History of Rh. fever without Ht. disease. | |
---|---|---|---|---|
Boys | 6500 | 4 | 18 | 27 |
Girls | 5799 | 9 | 22 | 28 |
The percentage of boys with heart disease was 0.339, and the
percentage of girls 0.535. Of the boys with a previous history of
rheumatic fever, 12.9 per cent. had heart disease; and of the girls, 24.4
per cent. So that heart disease is more prevalent in girls, and is much
more likely to follow rheumatic fever in girls than boys.
The above figures may be arranged in a four-fold table, including
both boys and girls:—
TABLE XXXIX. HISTORY OF RHEUMATISM.
Absent. | Present. | Total. | ||
---|---|---|---|---|
Heart Disease | Absent | 12181 | 55 | 12236 |
Present | 50 | 13 | 63 | |
Total | 12231 | 68 | 12299 |
As, however, the parents were not present at 43 per cent. of the
inspections of these children, and, as in these cases a history of rheumatism
could not be obtained even if they had had it, we must remove them from
the table, and, of course, they must be removed from the first column
only. So that the table which includes only those children whose parents
were present at the medical inspection becomes:—
TABLE XL. HISTORY OF RHEUMATISM.
Absent. | Present. | Total. | ||
---|---|---|---|---|
Heart Disease | Absent | 6920 | 55 | 6975 |
Present | 23 | 13 | 36 | |
Total | 6943 | 68 | 7011 |
