  1. ρ: Spearman correlation coefficient, SD Standard deviation
  2. Data are expressed as the Spearman correlation coefficient when studying the correlation between the MLHFQ social subscales and SF-12 components, and as the mean (SD) when comparing the MLHFQ social subscales as a function of emergency department attendance, or readmission during the previous 6 months
  3. The scores for the social dimension range from 0 to 15 for that proposed by Lambrinou, from 0 to 20 for that proposed by Garin, and from 0 to 30 for that proposed by Munyombwe, with higher scores indicating worse health status. The scores for the SF-12 dimensions range from 0 to 100, with higher scores indicating better health status
