Table 5 Differences between patients with high (≥68) or low (< 68) SOC concerning quality of life.

From: Outcome and clinical changes in patients 3, 6, 12 months after a severe or major hand injury - can sense of coherence be an indicator for rehabilitation focus?

  1. a Population norms were obtained from the Swedish SF-36 database for population norms (n = 8930) and n = 45 were age and gender matched with individuals (n = 1180). b Effect size for SF-36 was calculated with mean change in score, three months to follow up after twelve months, divided by standard deviation of the three months score. c Z-scores (individual value minus mean value of populations norms divided by SD from the population norms) were calculated for all SF-36 parameters at 12 months. SF-36 (0-100) higher score indicates a better health status 0 (poor health) to 100 (optimal health). d Differences between high and low SOC (Mann Whitney). * Different from the population norms (Wilcoxons Signed Ranks Test).
