“…All 39 remaining articles were then downloaded as PDF files for full-text peer review and discussion [ 13 - 16 , 21 , 22 , 38 - 70 ]. We excluded 23 articles after the full-text screening for the following reasons: (1) a device or program feasibility study (n=2) [ 66 , 69 ], (2) duplicated article (n=1) [ 21 ], (3) not an intervention study (n=5) [ 39 , 43 , 47 , 49 , 53 ], (4) not a mobile phone intervention (n=7) [ 14 , 42 , 48 , 56 , 58 , 63 , 68 ], (5) no sleep outcome (n=3) [ 16 , 44 , 65 ], and (6) a protocol or trial (n=5) [ 40 , 45 , 50 - 52 ]. The entire selection procedure was independently performed by two researchers (JCS and JK), and then the research team resolved differences by discussion.…”
