TABLE 3.

Relationship between molecular characteristics and CNV events of m⁶A regulatory genes in BLCA patients (n = 409)

			Without mutation nor CNV*	With mutation and/or CNV*	χ²	p
TP53	n = 409	wt	35	177	20.552	<0.001
		alteration	6	191
TNN	n = 409	wt	32	181	12.315	<0.001
		alteration	9	187
MUC16	n = 409	wt	37	254	8.094	0.004
		alteration	4	114

Chi‐square test was applied for analysis and p < 0.05 was considered significant.

^*With mutation and/or CNV: Cases have mutant or CNV or mutant and CNV, confirmed through TCGA database. Without mutant nor CNV: Cases with neither mutant nor CNV, confirmed through TCGA database. Ambiguous variables (Nx, Mx, N/A and Gx) were excluded from chi‐square test or non‐parametric test.
