21.   The ratio of mean mortality rate was smaller in boys than in girls but the difference was not significant.

22.   During the observation period heparin treatment induced a significant reduction in reinfarction rate, general mortality rate, and cardiovascular mortality due to thromboembolic events.

23.   The higher APACHE II scores of patients in the second ICU indicate that the patients were more severely ill, as confirmed by the higher mortality rate.

24.   Neither mortality rate was as low as that achieved by the combination of streptokinase and aspirin without heparin.

25.   Overall, their mortality rate was higher than that of patients who received subcutaneous heparin but lower than that of those receiving no heparin.

26.   With the arrival of western man, who took spices and introduced new crops, has come plantation agriculture and a reduction in the mortality rate.

27.   He also warned, however, that reduced mortality rates will mean that the population as a whole will continue to grow.

28.   This concentration of fish causes social stress, disease and oxygen depletion, which may in turn cause high mortality rates especially in hot weather.

29.   Every clinic conducts regular surveys to monitor the effects of the programme, proving that infant mortality rates have dropped, whilst scabies and bronchitis have decreased too.

30.   Age-specific mortality rates are interesting in themselves but cumbersome as a means of summarizing death rate patterns.
