Design outcomes

Primary

Measure	Time frame
Percentage of people with altered alkaline phosphatase biomarker levels. Timepoint: Measurement before and after intervention. Method of measurement: The Pars Azmoun Company kit is used to measure alkaline phosphatase levels with a sensitivity of 4 international units.;Percentage of people whose albumin biomarker levels were adjusted. Timepoint: Measurement before and after intervention. Method of measurement: Serum albumin was also measured using a chemical colorimetric method (bromcresol green).;Percentage of people with altered calcium biomarker levels. Timepoint: Measurement before and after intervention. Method of measurement: Serum calcium was measured by chemical colorimetric method (cresolphthalein).;Percentage of people with altered vitamin D biomarker levels. Timepoint: Measurement before and after intervention. Method of measurement: Vitamin D levels are measured by high-performance liquid chromatography.;Percentage of people whose weight and BMI were adjusted. Timepoint: Measurement before and after intervention. Method of measurement: The weight of the subjects was calculated using a Seka scale and BMI was calculated by dividing body weight by the square of height.	—
