Table 4 Simulation analysis – effect of alternative assumptions for weight progression

From: Assessing the reliability of self-reported weight for the management of heart failure: application of fraud detection methods to a randomised trial of telemonitoring

Standard deviation for daily weight change Assignment of EDP patients (%) Assignment of NEDP patients (%) Proportion of people in A1-A4 with NEDP (%)
A0 A1-A4 A0 A1-A4
0 (Weights constant over time) 100.0 79.1 20.9 79.1 85.0
0.05 100.0 83.8 27.8 87.2 85.5
0.1 100.0 83.9 33.2 92.6 86.2
0.5 100.0 10.4 24.8 75.4 97.6
1.0 100.0 0.2 11.0 43.0 99.9
Limiting scenario (from Table 1) 100.0 0.0 5.9 23.5 100.0
  1. Note: Assumes 15% of patients have EDP, 30% of the time. Patients submitted weight readings on 162 days. Based on 10,000 replications of the simulation experiment
