Differences in texture features in GLRL category between each pair of groups of preinvasive lesions, MIAs and IPAs

Texture features	P value
	Preinvasive lesions vs.MIAs	Preinvasive lesions vs. IPAs	MIAs vs. IPAs
GLRL, gray-level run length matrix; MIAs, minimally invasive adenocarcinomas; IPAs, invasive pulmonary adenocarcinomas; RLN, run length nonuniformity; RP, run percentage; LGLRE, low gray level run emphasis; HGLRE, high gray level run emphasis; SRLGLE, short run low gray level emphasis; SRHGLE, short run high gray level emphasis; LRLGLE, long run low gray level emphasis; LRHGLE, long run high gray level emphasis; LRE, long run emphasis; GLN, gray level nonuniformity; SRE, short run emphasis. P value was calculated with Kruskal-Wallis rank sum test followed by Dunn-Bonferroni post hoc test.
