“…Of the 47 full texts that were read, only nine studies met all of our inclusion criteria [ 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 ]. Sixteen records were excluded because they were determined not to be reporting results from controlled interventional studies [ 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 ]. Eight records were excluded because outcomes of the intervention were only measured in a laboratory environment [ 53 , 54 , 55 , 56 , 57 , 58 , 59 , 60 ].…”
