Preliminary work suggests that, after a 3-day training session, observers have acceptable IRR scores when using the TDOP (Hora et al., 2013).
Items 7 and 8 had poor kappa values (kappa = 0.00) due to skewed frequencies but acceptable observer agreement (77% respectively 85%).
The intra-observer agreement was acceptable, but inferior to the inter-observer agreement, especially by MS. This could be explained by a long period (>3 months) between the two measurements and by the first but not the second image analysis being preceded by a calibration session.
Poor inter-observer agreement, but acceptable reliability of measurements may seem to be a puzzling result.
TEM: Technical error of measurement CV: Coefficient of variability MUAC: Mid-upper arm circumference TS: Triceps skinfold According to the reliability coefficient, height and weight inter-observer variability were acceptable in both studies.
In the femur, the inter-observer variations were acceptable with a bias of 15 mm (95% CI -60 to 89) and 7 mm (95% CI -129 to 144) by CAS and MS, respectively.
In the cases when the SPs were negative and the observers gave an acceptable ACIR score (PON group), the reasons for this discrepancy were related to the trainees' poor performance in providing care and mitigating the patient's cancer concerns.
The 3DE values showed excellent intra-observer variability (<3%) and still acceptable inter-observer variability (<13%).
Linear quadratic regulat or theory (LQR) is used to design the observer gain, which provides acceptable estimated values.
This approach allows us to avoid a more complex structure for the observer, and yields an acceptable performance and the elimination of bulky position sensor systems.
A critical analysis of these criteria shows acceptable inter-observer variability, good specificity, but poor sensitivity.
