Fig. 4From: Value of blood oxygenation level-dependent magnetic resonance imaging in early evaluation of the response and prognosis of esophageal squamous cell carcinoma treated with definitive chemoradiotherapy: a preliminary studyBox-whisker plots of R2* values in ESCC at pre- and post-dCRT in the CR group. The horizontal line through each box represents the median value and the box represents data of 95% confidence intervals. Graph shows that R2* values of esophageal cancer had significantly increased at 2–3 weeks post-dCRT in the CR group (P = 0.003)Back to article page
