The study investigates T2DM patients who have not had surgery or cardiac event in the last 3 months, between the ages of 40 and 64 years, with T2DM diagnosis between the last 1 and 10 years and oral antidiabetic therapy for at least 1 The study design is a single-blinded randomized, controlled study, and was conducted in the Diabetes Polyclinic of the Istanbul University Medical Faculty Hospital.

Patients randomly assigned to the intervention group, in addition to traditional treatment received three to four informative SMS messages per week during the 6-month period, while the control group was followed in accordance with the traditional treatment schedule.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Informative messagesOther

    In addition to their standard treatments, an informative SMS (text message) on diabetes was sent to the intervention group three to four times a week for six months.

    The short messages were in the form of a short sentence for the subject and the predicate. The messages sent have been prepared in such a way that they do not exceed 1 SMS quota and are less than 160 characters on mobile phones.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Fasting blood glucose

  7. Physical Activity level

    The International Physical Activity Questionnaire (IPAQ) was used to evaluate the physical activity level of the participants at the beginning of the study.

    This measure assesses the types of intensity of physical activity and sitting time that people do as part of their daily lives are considered to estimate total physical activity in MET-min/week and time spent sitting. The higher scores mean a better outcome.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Fasting blood glucose (time frame: Beginning). The study lists 15 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04733612, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
