Table 7 Analysis of computer-aided tomographic scan data on 50 patients via PIX or PLAN with two replicates

From: Comparison of two dependent within subject coefficients of variation to evaluate the reproducibility of measurement devices

  PIX (l = 1) PLAN (l = 2)
  Estimate SE Estimate SE
μ l 1.41 0.074 1.79 0.056
