Table 3 Numbers of participants (absolute risk %) who had achieved a minimally clinically important difference in functional independence and health-related quality of life from admission to assessment at discharge, 6 months and 12 months

From: Additional Saturday rehabilitation improves functional independence and quality of life and reduces length of stay: a randomized controlled trial

Outcome Time point Intervention Control Relative risk difference (95% CI) Number needed to treat (95% CI)
Functional independence (FIM) Discharge 256 (52) 220 (44) 1.17 (1.03 to 1.34)* 13 (7 to 71)
6 months 274 (55) 261 (52) 1.06 (0.94 to 1.19) 33 (−32 to 11)
12 months 284 (57) 266 (53) 1.07 (0.96 to 1.20) 25 (−47 to 10)
Health-related quality of life (EQ-5D) Discharge 262 (53) 222 (44) 1.18 (1.04 to 1.34)* 12 (7 to 45)
6 months 287 (58) 243 (49) 1.19 (1.06 to 1.34)* 11 (7 to 33)
  12 months 289 (58) 262 (52) 1.11 (1.00 to 1.24) 17 (−326 to 8)
