Telemedicine had no convincing effect on quality of life , mortality or hypoglycemia .
INTERPRETATION : Compared with usual care , the addition of telemedicine , especially systems that allowed medication adjustments with or without text messaging or a Web portal , improved HbA1C but not other clinical ly relevant outcomes among patients with diabetes
BACKGROUND : Telemedicine , the use of telecommunications to deliver health services , expertise and information , is a promising but unproven tool for improving the quality of  diabetes care  .
We summarized the effectiveness of different methods of telemedicine for the management of diabetes compared with usual care .
A method for assessing the quality of a randomized control trial.
A system has been constructed to evaluate the design , implementation , and analysis of  r and omized control trials ( RCT ) . The degree of quadruple blinding ( the r and omization process , the physicians and patients as to therapy , and the physicians as to ongoing results ) is considered to be the most important aspect of any trial . The analytic techniques are scored with the same emphasis as is placed on the control of bias in the planning and implementation of the studies . Description of the patient and treatment material s and the measurement of various controls of quality have less weight . An index of quality of a RCT is proposed with its pros and cons . If published papers were to approximate these principles , there would be a marked improvement in the quality of r and omized control trials . Finally , a reasonable st and ard design and conduct of trials will facilitate the interpretation of those with conflicting results and help in making valid combinations of undersized trials
