Time perspective

The relationship between the observation period and the time of patient enrollment. Time perspective can be prospective: looking forward using periodic observations usually collected following patient enrollment, or retrospective: looking back using observations usually collected prior to patient selection and enrollment.

Type 2 diabetes

Diabetes means your blood sugar (glucose) level is too high. Type 2 diabetes, the more common type, means your body does not make or use the hormone insulin properly. Insulin helps glucose get into your cells to give them energy. Without insulin, too much glucose stays in your blood and over time this can lead to serious problems of the heart, eyes, kidneys, nerves, and gums and teeth.

Tyrosine kinase inhibitor (TKI)

A drug that blocks the action of enzymes called tyrosine kinases. Tyrosine kinases affect many cell functions, including cell signaling, growth, and division. These enzymes may be overactive or found at high levels in some types of cancer cells, and blocking them may help keep cancer cells from growing. TKIs are a type of targeted therapy.
