Group 2 names the comparator: control.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Text Messages | Short text messages related to healthy lifestyle will be sent to half the subjects three times per week, in addition to one off 'one-to-one structured education' during the study period.~Short text messages: In addition to structured education on healthy lifestyle provided at baseline, subjects in the arm will receive short text messages containing educational, motivational and supportive content on diet, physical activity, and smoking (if appropriate) during the study period. The content will be appropriate to the stage of the transtheoretical model of behavioural change that the subject is in. This will be assessed by questionnaire at each visit to clinic. | 0 | 1,031 | EG000 |
