Abstract

Objectives: To compare the safety and efficacy of adding insulin glargine or neutral protamine Hagedorn ( NPH ) insulin to existing oral antidiabetic drug ( OAD ) regimens in adults with type 2 diabetes mellitus. Design: Pooled analysis of data from five randomized controlled trials with similar designs. Setting: Three hundred forty‐two centers in more than 30 countries worldwide. Participants: Randomly selected individuals aged ≤ 80 with a body mass index ≤ 40 kg/m 2 and a glycosylated hemoglobin ( HbA1c ) level of 7.5% to 12.0%. Measurements: Fixed‐ and random‐effects models were used to compare outcomes after 24 or 28 weeks of treatment (insulin glargine, n = 1,441; NPH insulin, n = 1,254) according to age (≥65, n = 604 vs < 65, n = 2,091) and age based on treatment (e.g., ≥65 receiving insulin glargine vs NPH insulin). Outcomes included change in HbA1c , fasting blood glucose ( FBG ), insulin dose, and hypoglycemia incidence and event rates. Results: At end point, participants aged 65 and older receiving insulin glargine had greater reductions in HbA1c and FBG than those receiving similar doses of NPH insulin. In contrast, for participants younger than 65, there were no statistically significant differences in reductions in HbA1c or FBG between insulin glargine and NPH insulin. Daytime hypoglycemia rates were similar in all groups, although the rates of nocturnal symptomatic and severe hypoglycemia were lower with insulin glargine than NPH insulin. Conclusion: Addition of insulin glargine to oral antidiabetic drugs in older adults with poor glycemic control may have modestly better glycemic benefits than adding NPH insulin, with low risk of hypoglycemia.

  • Addition of long-acting insulin was similarly effective in achieving A1C goals for older patients with type 2 diabetes (mean age 69 years) in a series of trials, with no greater rates of hypoglycemia than in younger patients (mean age 53 years).

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
