 Favourable | P < 0.10 in favour of the intervention, or described as ‘statistically significant’ |
 Neutral | P > 0.10, or described as ‘no difference between groups’ |
 Unfavourable | P < 0.10 in favour of the comparator, or described as ‘favouring the non-intervention comparator’ |
Conclusions | |
 Positive-strong | Authors state that there is clear evidence for the effectiveness of the intervention, and no further research is needed |
 Positive-weak | Authors state that there is evidence for the effectiveness of the intervention, but more research is needed to confirm the findings |
 Neutral | Authors state that there is no or insufficient evidence about whether the intervention is effective or not, and more research is needed to reach a conclusion |
 Negative-weak | Authors state that there is evidence against the use of the intervention, but more research is needed to confirm the findings |
 Negative-strong | Authors state that there is clear evidence against the use of the intervention, and no further research is needed |
