Planned meta-regression analyses were used to examine whether any between-study heterogeneity could be explained by format of intervention (group or individual) and measures of study quality (sequence generation, allocation concealment, blinding of outcome assessors), as these have been suggested by previous analyses to influence effect size.
There will be no exclusion criteria regarding other intervention elements, the duration of intervention, the format of intervention delivery (eg, curricula based or internet based) or the intervention administration (eg, the intervention could be delivered by school staff, research staff, community members or students).
The trial design offers women a standard "dose," or number, duration, frequency, and format of intervention contacts.
Issues related to intervention delivery are presented in Table 4, including the location, duration, format of intervention delivery, and the delivery agent.
In terms of responsive PPI, liaison with relevant patient panels or groups may be particularly helpful when more diverse perspectives or wider consensus is needed; individuals might also consider whether surveys (eg, of support group members) would be useful in answering 'burning questions', for example, regarding the acceptability of timing or format of interventions or data collection.
Many settings have particular guidelines or requirements for the development and formatting of intervention plans.
The standard, single formats of intervention effectiveness are: absolute risk reduction (ARR), relative risk reduction (RRR) and number needed to treat (NNT).
Duration/length and formatting of interventions.
This proposal has been developed collaboratively with our PAG, and their comments and suggestions about the format of the intervention and parent/carer materials have informed for both the intervention and the final design of the feasibility study.
Also, the semi-structured format of the intervention was positively evaluated as this enabled them to tailor the intervention to the individual needs and wishes of patient and caregiver.
