The OBSTACLE Hypoglycemia Study (MK-0000-158)
1 april 2015 uppdaterad av: Merck Sharp & Dohme LLC
Prospective Observational Study to Assess Correlation Between Glycemic Control and Hypoglycemia in Patients With Type 2 Diabetes Treated With Sulfonylurea
This study will assess the correlation between glycemic control and the hypoglycemia symptom score in patients with Type 2 diabetes, 12 weeks after addition of a sulfonylurea to an ongoing regime of oral hypoglycemic agents.
Studieöversikt
Detaljerad beskrivning
Patients will be evaluated for participation in the study during their usual visit to participating diabetes care clinics.
Addition of sulfonylurea will be an unbiased decision of the participating physicians based on the clinical needs of the participating patients.

All participants
Participants with type 2 diabetes mellitus (T2DM) who had sulfonylurea treatment added to an on-going regime of oral hypoglycemic agent(s).

Correlation Between HbA1c Values at Week 12 and Hypoglycemia Scores
Tidsram: Week 12
|
Coefficient of correlation was measured using a linear regression analysis for the association between two variables, HbA1c values at Week 12 and hypoglycemia scores.
A negative correlation coefficient indicates that as one value increases the other value decreases, and vice versa.

Hypoglycemia Symptom Score by Sub-group (Demographic/Disease Parameters)
Tidsram: Week 12
|
Sub-group analyses of mean hypoglycemia symptom score.
Participants were grouped based on gender, age, hypoglycemia severity, body mass index, duration of diabetes, and number of oral hypoglycemic agents.
Hypoglycemia symptom score (measured by Stanford Hypoglycemia Questionnaire) is a score on a scale with a possible range of 0 (best) to 7 (worst).
The questionnaire was administered by the physician at Week 12.

Sub-group analyses based on Karl pearson coefficient of correlation for HbA1c values at Week 12 and hypoglycemia score.
Participants were grouped based on gender, age, body mass index, and duration of diabetes.

Coefficient of correlation as measured using linear regression analysis for association between two variables, HbA1c values at baseline and hypoglycemia scores.
A positive correlation coefficient indicates that as one value increases the other value increases, or as as one value decreases the other value decreases.
