Table 4 PosturePrint® reliability with a liberal ICC method (ICC3,1). Forty student volunteers at a university were evaluated, with a posture digitizer, twice by three examiners, with a one-day delay.

From: Three dimensional evaluation of posture in standing with the PosturePrint: an intra- and inter-examiner reliability study

  2. † ICC = Intra- or inter-examiner correlation coefficient
  3. ‡ 95% C.I. = 95 percent confidence interval
  4. § MADOM = Mean absolute differences of observers' measurements
  5. || N/A = Not applicable, means the assumption of a normal distribution was violated by many identical values, and thus ICCs are not appropriate for this data.
