  1. a Follow-up scores adjusted for baseline. Figures presented for the QELS are marginal means
  2. b Difference adjusted for values at baseline reported as the Network minus the Control group
  3. c Analysis performed with variable on log scale. Difference represents the ratio of outcome in the Network group relative to the Control group
  4. d Difference assessed by time by group interaction. Reported as the Network minus Control group
  5. e Odd ratios
  6. f Summary statistics are the number/percentage of subjects responding either Sometimes or Always
