Fig. 4From: Improved results of LINE-1 methylation analysis in formalin-fixed, paraffin-embedded tissues with the application of a heating step during the DNA extraction processGastric cancer patients (n = 476) were divided into four groups according to their tumoral LINE-1 methylation levels and its association with dissected-free survival (a) and overall survival (b) was observed. Q1, Q2, Q3, and Q4 are in the order of increasing LINE-1 methylation levelsBack to article page
