For OS, Cox analysis results (Figure S4) revealed that some cancers, including ACC (Figure 3A), KIRC (Figure 3B), KIRP (Figure 3C), LGG (Figure 3D), LIHC (Figure 3E), LUAD (Figure 3F), MESO (Figure 3G), OV (Figure 3H), SARC (Figure 3K), SKCM (Figure 3L), and UCEC (Figure 3N), exhibited worse prognosis with higher DBF4B expression; conversely, for PAAD (Figure 3I), READ (Figure 3J), THYM (Figure 3M), the opposite was observed. This evidence concerns the gene DBF4B and cancer.
