These criteria include information on sampling method, outcome measurement, intervention, and reporting of biases and limitations.
A comprehensive overview about procedures and results is presented in Table 4. † "Same day" refers to a single session consisting of pre-intervention measurement, intervention and post-intervention measurement.
Intervention clinic patients with baseline A1C ≥7% significantly improved glycemic control at the last postintervention A1C measurement, intervention effect of −0.19% mean A1C (P = 0.034) and +6.7% in A1C <7% goal achievement (P = 0.0099).
Since patients who meet the selection criteria are being seen every three months for routine diabetes monitoring, it was decided to schedule all study phases (recruitment, baseline measurements, interventions and final measurements) to be carried out at the routine three-monthly appointments.
Al-Damluji also welcomed the prospect of the development of an impact measurement metric which measures interventions and spending in different areas, noting that the Disability Adjusted Life Year offered a way of comparing the impact of different healthcare interventions.
The weaknesses identified by the NRCNA list included use of unanesthetized animals, lack of blood concentration measurements, intervention tested in only one species, oral CCB administration, autopsy not conducted, lack of allocation concealment, and blinded assessment.
One RCT was small (n = 45) and compared a combination of nutrition counselling (NC) and serum cholesterol measurement (SC) interventions with no intervention.
Then the two post-intervention tests (intervention vs control group) were compared expecting to find a greater post-intervention measurement in the intervention group than the control group due to the effect of the intervention package.
The study quality of the three RCTs was high; however, measurement outcomes, interventions, and follow-up time periods differed across studies.
