Study characteristics
Methods	Evaluation of the effectiveness of mobile diabetes management system with social networking and cognitive behavioural therapy (CBT) for T2D RCT (NA clusters and NA providers), conducted in 1) All participants were from a clinic in Saudi Arabia‐Damman. 2) Mobile diabetes management system operated remotely through the SANAD system. Figure 1 shows that diabetic nurses and CBT therapists were involved in the delivery of the intervention. In Saudi Arabia. 2 arms: 1) Control (conventional diabetes treatment) (control arm) and 2) Intervention (SANAD system) (intervention arm)
Participants	Control arm N: 10 Intervention arm N: 10, NA, NA Diabetes type: 2 Mean age: NR ± 6.45 % Male: 75 Longest follow‐up: 6 months
Interventions	Control arm: (conventional diabetes treatment) Intervention arm: (SANAD system) 1) Electronic patient registry 2) Patient education
Outcomes	1) Glycated haemoglobin
Funding source	No information of funding source. "Some of the limitations of this study that may affect internal and external validity include the small sample size (n = 20), which was due to limited funding"
Notes	—
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	Not reported
Allocation concealment (selection bias)	Unclear risk	Not reported.
Patient's baseline characteristics (selection bias)	Low risk	See Table 1, education lower in control group, but all other characteristics balanced.
Patient's baseline outcomes (selection bias)	Low risk	Table 1) Baseline HbA1c P value > 0.05
Incomplete outcome data (attrition bias)	Low risk	1 patient lost in the intervention group (1/10 or 10%). None lost in the control group.
Blinding of participants and personnel (performance bias) and of outcome assessors (detection bias)	Low risk	Objective measure for HbA1c.
Selective reporting (reporting bias)	Unclear risk	No registered protocol. Methods match outcomes.
Risk of contamination (other bias)	Unclear risk	Patient randomised. Both groups were monitored by the same staff. Unlikely that the control group received the SANAD intervention.
Other bias	Low risk	No evidence of other bias.
