Comparison between patients and Family members at each time point.

^a p = 0.016

^b p = 0.001

^c p<0.001

^d p = 0.076

^e p = 0.013

^f p = 0.002

^g p = 0.019

Comparison following time for patients: HADS total score and subscales: p<0.001; IES score p<0.001

Comparison following time for family members: HADS total score and anxiety subscale: p<0.001; HADS score depression subscale: p<0.001; IES score p = 0.052

HADS denotes Hospital Anxiety and Depression Scale and IES denotes Impact of Event Scale.
