Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Randomization will be done by person who is not involved in enrolling the patients and writes intervention group(A or B) in sealed opaque envelopes after determining its sequence. thereafter people who are undertaking enrolling, after checking the inclusion and exclusion criteria, open the envelope to determine the intervention group of each patient.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Each group(laser/sham) are named A or B by someone who is not involved in enrolling, evaluation and analysis. According to randomization table, sequence of block will be defined. (Permuted block randomization)
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
