Fig. 1From: A strategy for evaluating pathway analysis methodsGene Expression Omnibus (GEO) dataset sample size distribution. The majority of datasets deposited in GEO contain a small number of samples. Over 34% of datasets deposited in GEO before 2016 contain ≤6 samples, and over 57% of them contain ≤12 samples. This distribution remains mostly the same for datasets added to GEO in 2016Back to article page
