(A) Bland Altman plot of inter-day (baseline -1 hr) repeatability of C2 measurement with KoKo Digidoser N = 39. (B) Bland Altman plot of inter-day (baseline -1 hr) repeatability of C2 measurement with Mefar dosimeter N = 39. Intra-individual differences (n = 38) between mean log C2 measured at baseline and 1 hr post baseline plotted against the mean of the sum scores. On each plot, the central line represents the mean of the intra-individual differences, and the flanking lines represent the 95% limits of agreement.
