Fig. 2From: Circulating miR-21 as a prognostic biomarker in HCC treated by CT-guided high-dose rate brachytherapyWaterfall plots illustrating miR dynamics per individual study subject for miR-21 (a) and miR-210 (b). To enable optimized depiction (i.e. decreasing miR values displayed as negative numbers), 2−ΔΔCт values between 0 and 1 (implicating decrease) were transformed applying the formula: 1/− (2−ΔΔCт). Note the significant increase of miR-21 in non-respondersBack to article page
