Table 2.

Distribution of recirculated questionnaires and short-term outcome. Shown are patients’ age and outcome stratified by different subgroups: all PM SAH patients (n = 37), patients without subsequent rehabilitation (n = 24), patients with subsequent rehabilitation (n = 13) and a matched pair group of patients without subsequent rehabilitation (n = 13). To minimize the influence of selection, a matching procedure was necessary. WFNS grade and age were used as matching parameters.

Characteristics	All PM SAH	Without Subsequent Rehabilitation	With Subsequent Rehabilitation	p (with vs. without Rehabilitation)
No. of patients	37 (100%)	24 (65%)	13 (35%)	NS
mean age ± SD	55.1 ± 9.6	53.7 ± 10.8	57.8 ± 6.2	NS
Outcome at discharge (mean mRS ± SD)	1.56 ± 0.64	1.36 ± 0.74	1.7 ± 0.5	NS
short-term outcome (mean mRS ± SD)	0.6 ± 0.59	0.54 ± 0.59	0.8 ± 0.6	NS
Improvement from discharge to short-term outcome (6 months)	0.69	0.82	0.9	NS
p (mRS discharge vs. mRS 6 months FU)	NS	NS	<0.001

PM SAH, perimesencephalic subarachnoid hemorrhage; NS, not significant (p > 0.05); SD, standard deviation; mRS, modified Rankin scale (mRS); FU, follow-up.
