Fig. 2From: Role of barium enema examination for the diagnosis of submucosal invasion depth in T1 colorectal cancersCorrelation between values of wall rigidity under the barium enema examination profile view and depth of submucosal (SM) invasion. a: Correlation between horizontal rigidity and depth of SM invasion. The value of horizontal rigidity is moderately correlated with depth of SM invasion (y = 1.78x + 2.55, r = 0.626, P = 0.0001). b: Correlation between vertical rigidity and depth of SM invasion. The width of vertical rigidity is moderately correlated with depth of SM invasion (y = 0.71x + 0.69, r = 0.482, P = 0.0001)Back to article page
