CI = confidence interval; *Positive differences indicate that the incidence rate for the sitagliptin group is higher than the incidence rate for the non-exposed group. "0.0" and "-0.0" represent rounding for values that are slightly greater and slightly less than zero, respectively.

Includes studies in which a sulfonylurea was an active comparator or a background agent.
