PRIMARY outcome

Timeframe: 7 days

Because of reports of fever in patients wiht zinc overdoses, we monitored patients for new fever while on supplementation

SECONDARY outcome

Timeframe: 7 days

Patients were assigned a score based on glucose range to take into account the degree of hyperglycemia as well as the need for insulin over the course of the 7 day study period. This score is an ordinal scale ranging from 1 to 5, with a score of 1 indicating no hyperglycemia, and 5 indicating severe hyperglycemia despite insulin administration.
