From: Psychometric evaluation of a caregiver diary for the assessment of symptoms of respiratory syncytial virus

GRCD Domain	Day 13 to Day 14 ICC (95% CI)	Alpha Last Day	Effect Size^a	Effect Size^b	SRM^a	SRM^b
Cough	0.77 (0.61, 0.87)	0.94	−2.83	−4.40	−1.53	−2.72
Respiratory	0.81 (0.68, 0.90)	0.78	−2.73	−4.14	−1.69	−3.17
RSV symptoms	0.94 (0.89, 0.97)	0.84	−2.67	−4.16	−1.65	−3.16
Behavior impact	0.43 (0.13, 0.66)	0.84	−2.08	−2.70	−1.88	−2.82
Global	0.90 (0.82, 0.95)	0.84	−2.72	−3.91	−1.96	−3.49

CI Confidence interval, ICC Intraclass correlation coefficient, SRM Standardized response mean
^aComputed using change from first day to seventh day
^bComputed using change from first day to last day
