“…The randomised controlled study [ 84 ] identified for this review scored poorly (25%) due to lack of description of participant allocation, < 80% reporting of outcome data and a high rate participant attrition (> 20%). Quasi experimental approaches were utilised in thirteen [ 86 , 88 , 92 , 94 , 95 , 97 – 104 ] of the quantitative, outcome studies, ( n =12) [ 86 , 88 , 92 , 94 , 95 , 97 – 101 , 103 , 104 ] of these scored more than 50%. Seventy-one percent [ 71 , 85 , 87 , 90 , 91 , 93 ] ( n = 5) of the quantitative descriptive studies scored 50% or more.…”
