Reasons for this difference include reduced incidence of hypoglycaemia, easier administration and more rapid action against circulating and sequestered parasites.

The direct benefits of the Clean Air Act from 1970 to 1990 include reduced incidence of a number of adverse human health effects, improvements in visibility, and avoided damage to agricultural crops.

Safety parameters included incidence of treatment-limiting toxicities (clinical and laboratory adverse events); and change from baseline in selected laboratory variables at weeks 4, 8, 12 and 24.

Morbidity measures include incidence rate, prevalence and cumulative incidence.

These include elevated incidence of cancer, disruption of the immune and hormonal systems, sexual abnormalities and stunted fetal growth.

These include incidence and severity of nausea and vomiting (N&V) during past courses of chemotherapy, history of chronic alcohol use, age, and gender.

These numbers do not include incidence or prevalence of "Acquired Brain Injury" (ABI) which can occur with anoxia or stroke.
