  • The p values refer to paired t test analysis from initiation to follow-up values within each group.

  • AVAPS, average-volume-assured pressure support; ESS, Epworth Sleepiness Score; FSS, fatigue severity score (total=56; higher score indicates greater level of fatigue); HRQL, health-related quality of life; PS, pressure support; SRI-AS, Severe Respiratory Insufficiency questionnaire attendant symptoms and sleep; SRI-AX, Severe Respiratory Insufficiency questionnaire anxiety; SRI-PF, Severe Respiratory Insufficiency questionnaire physical functioning; SRI-RC, Severe Respiratory Insufficiency questionnaire respiratory complaints; SRI-SR, Severe Respiratory Insufficiency questionnaire social relationships; SRI-SS, Severe Respiratory Insufficiency questionnaire summary scale (total=100; higher score indicates higher quality of life); SRI-WB, Severe Respiratory Insufficiency questionnaire psychological wellbeing; SRI-SF, Severe Respiratory Insufficiency questionnaire social functioning; VAS, visual analogue scale (higher score indicates greater quality of life).
