Demographic and clinicopathological data of the ALS cases (n = 31) with a disease duration of <2 years (short survival) or 4–7 years (longer survival) included in this study

	Short survival	Longer survival	p value
N (% male)	15 (67%)	16 (63%)	0.8
Age at death (years)	66 ± 2	70 ± 2	0.3
Disease duration (years)	1 ± 0.2	5 ± 0.2	<0.001
Postmortem delay (hours)	27 ± 5	26 ± 3	0.9
Prevalence UL/LL/Bulbar (%)	42/25/33	36/50/13	0.3
ALS-TDP stage (10)	2.8 ± 0.4	2.3 ± 0.3	0.3

Data for mean age, disease duration, postmortem delay, and ALS-TDP stage are presented as mean ± SE. All other data are presented as frequency of occurrence within the survival group.
