Between 0–5 months Baseline level
Whether it works:
It works but not scientifically proven −14.66 (−18.88 – -10.44) −10.41 (−15.52 – -5.30) −8.49 (−13.18 – -3.80) −19.68 (−33.83 – -5.53) −10.89 (−14.63 – -7.14)
Experts say it works elsewhere in the NHS −1.65 (−16.82 – 13.51) −4.14 (−8.20 – -0.09) −0.91 (−4.77 – 2.96) −4.79 (−15.39 – 5.81) −3.13 (−5.85 – -0.41)
It works and scientific studies confirm this Baseline level
Potential health benefits:
Moderate health (50%) Baseline level
Good health (75%) 15.45 (11.09 – 19.82) 9.51 (5.02 – 14.01) 9.20 (4.83 – 13.56) −0.71 (−12.31 – 10.89) 8.17 (5.10 – 11.24)
