To randomly allocate subjects to either the four groups, the following steps will be undertaken in the current study:
we need random numbers for 40 children in 4 intervention group (each group 10 participant)
the numbers are generated by https://www.randomizer.org/
4 data sets, 10 number per set, with unique numbers place markers within. The numbers 1 to 40 will correspond to the consecutive numbers of the referring patients based on the date of the medical record.
(example: Set #1
p1=4, p2=16, p3=13, p4=22, p5=28, p6=33, p7=30, p8=36, p9=35, p10=21
Set #2
p1=21, p2=4, p3=40, p4=15, p5=3, p6=35, p7=34, p8=23, p9=37, p10=7
Set #3
p1=34, p2=28, p3=9, p4=40, p5=20, p6=36, p7=7, p8=3, p9=5, p10=2
Set #4
p1=10, p2=5, p3=38, p4=24, p5=27, p6=30, p7=25, p8=7, p9=36, p10=34)
