Dichotomous outcomes

Relative risk^*

RR=R_Post,I/R_{Post, C}

Relative risk adjusted for baseline^*

RRAdj=(R_Post,I/R_{Post, C})/(R_Pre,I/R_{Pre, C})

Where R_{Post,I and} R_{Post, C} are defined above, and R_{Pre,I and} R_{Pre, C} are the respective risk of the outcome in the intervention and comparator groups pre‐intervention.

Risk difference^*

RD=R_Post,I ‐ R_{Post, C} where R_{Post,I and} R_{Post, C} are defined as above.

R_Post,I= risk of the outcome in the post‐intervention group.

R_{Post, C} =risk of the outcome in the comparator group post intervention.

R_Pre,I is the risk of the outcome in the intervention group pre‐intervention.

R_{Pre, C} is the risk of the outcome in the comparator groups pre‐intervention.

Continuous outcomes

Standardised mean difference^*

SMD=(Mean _Post,I ‐ Mean _Post,C )/SD _Pre,pooled

Relative percentage change post intervention^*

RPC=((Mean _Post,I ‐ Mean _Post,C )/Mean _Post,C )X100

Difference in means post‐intervention^*

DM=(Mean _Post,I ‐ Mean _Post,C )

Difference in mean change^*

DMC=(Mean _Post,I ‐ Mean _Post,C )‐(Mean _Pret,I ‐ Mean _Pre,C )

*Mean _Post,I is mean of post‐intervention groups.

Mean _Post,C is mean of post‐comparator groups.

SD _Pre,pooled is the pooled standard deviation of the two groups pre‐intervention.

Mean _Pret,I is mean of pre‐intervention groups.

Mean _Pre,C is mean of pre‐comparator groups.
