Boxplot analysis of the RBM22 ChIP-seq signals (g) and the elongation rate changes upon RBM22 knockdown (h) for the genes with different elongation rates in control cells. The 598 genes with computable elongation rates were divided into three groups based on elongation rate in control cells: low (rate < 1.87 kb/min), medium (1.87 kb/min < rate < 2.36 kb/min), and high (rate > 2.36 kb/min). The p values are determined using the two-tailed unpaired t-test (* p ≤ 0.05; ** p ≤ 0.01; *** p ≤ 0.001; **** p < 0.00001)
