diabetes2: Type 2 Diabetes Clinical Trial for Patients 10-17 Years Old

In JECheadle/RSOC317L: Data Sets and Supplemental Functions from David Diez's 'OpenIntro' Textbook

Description

Three treatments were compared to test their relative efficacy (effectiveness) in treating Type 2 Diabetes in patients aged 10-17 who were being treated with metformin. The primary outcome was lack of glycemic control (or not); lacking glycemic control means the patient still needed insulin, which is not the preferred outcome for a patient.

Each of the 699 patients in the experiment were randomized to one of the following treatments:

• continued treatment with metformin (coded as met)

• metformin combined with rosiglitazone (coded as rosi), or

• or a lifestyle-intervention program (coded as lifestyle).

Usage

data("diabetes2")

Format

treatment
