Table 4 Consistency of number of hazards by room and home after removing hazards with poor agreement (n = 20 homes)

From: Evaluation of the Home Environment Assessment for the Visually Impaired (HEAVI): an instrument designed to quantify fall-related hazards in the visually impaired

  1. ICC = intraclass coefficient; CI = confidence interval
  2. ICC agreement categories: 0.81–1.00 = almost perfect; 0.61–0.80 = substantial; 0.41–0.60 = moderate; 0.21–0.40 = fair; 0.00–0.20 = slight; <0.00 = poor 39
  3. Bold values indicate significant results
