AgeFactDB summary statistics of ageing factors as of 15 August 2013

Ageing factor type	Ageing relevance evidence
	Experimental	Computational	Both	Any
Gene	2594	14 437	581	16 450
Compound	91	–	–	91
Other ageing factor	58	–	–	58
Total	2743	14 437	581	16 599

Ageing factors can have both experimental and computational ageing relevance evidence because they may include a number of different observations. These examples are included both in the experimental and computational categories. Their total sum is thus given by Experimental + Computational–Both.
