  1. SIT Schirmer-I test, NRS numerical rating scale, OSDI ocular surface disease index, TBUT tear break-up time, CFS corneal fluorescein staining, CI confidence intervals
  2. aScoring is the sum of the totals divided by 8 (8 symptoms in total)
  3. bScoring was additive (0 [better outcomes] to 44 [worse outcomes]). Minimal clinically important difference: 13.9
  4. cTreatment acceptability was assessed by the chi-square tests. All participants (120) were included in the acceptability assessment and the participants who did not complete the treatments were all evaluated as a little difficulty in acceptability
