The numbers of the lost introns in each species are in the second columns of Tables 2 and 4, and the number of the conserved introns was 6252. The length of its ortholog represented the length of a lost intron, and that of orthologous introns represented that of the conserved introns for comparison. The P-value was computed by the Mann–Whitney U test. BH: Benjamini–Hochberg
