Fig. 3From: Agreement test of transcutaneous bilirubin and bilistick with serum bilirubin in preterm infants receiving phototherapyScatter and Bland Altman plot between TcB and TSB (a and b), Bilistick and TSB (c and d) at 48 h of phototherapy. Y equation = linear equation obtained from linear regression analysis. Y = estimated TSB, X = Bilirubin level of the device being tested () = average difference () = agreement limit () = tendency of average difference () = 0 point, standard to observe distance with red lineBack to article page
