Appendix 3. Planned methods archived for future updates of this review

Measures of treatment effect

Continuous outcomes

We will use standardised mean differences (SMDs) for continuous outcomes that are measured with similar, but not identical, instruments.

Unit of analysis issues

 

Cluster‐randomised trials

We do not anticipate finding cluster‐randomised trials.

Cross‐over trials

If we find any cross‐over trials, we will conduct a meta‐analysis to combine results using the inverse variance method as recommended by Elbourne 2002. In the case that data from a cross‐over trial are limited and restricted, we will use available data within the first phase, only up to the point of cross‐over. 

Repeated observations on participants

If studies report repeated observations on participants, we will extract time points closer to 3 and 6 months and at the end of the study.

Assessment of reporting bias

 

If we find enough studies (n = 10), we will draw funnel plots (effect size versus standard error) to assess the presence of small‐study effects. Although asymmetry may represent the relationship between trial size and effect size, it can also demonstrate publication bias. If we find funnel plot asymmetry, we will investigate clinical diversity as a possible explanation for asymmetry.

Subgroup analysis and investigation of heterogeneity

 

Assuming a sufficient number of included studies, we will undertake a subgroup analysis to explore the possibility of differential responses to aripiprazole based on:

  • age of participants (i.e. adult versus child);

  • dose of medication given (i.e. 5 mg dose versus 10 mg dose); and

  • intervention length (i.e. less than or greater than 1 year).

If data are presented in unuseable forms, we will attempt to contact study authors for raw data. If we cannot obtain these data, we will not include the study in the meta‐analysis but instead will describe the results individually.

Sensitivity analysis 

We will conduct sensitivity analyses to assess the impact of risk of bias on results in the event that we find a sufficient number of studies. For example, we will exclude studies rated as having high risk of bias for sequence generation or allocation concealment, or both, to find any impact on results of the meta‐analysis.

ABC: Aberrant Behavior Checklist; GRADE: Grades of Recommendation, Assessment, Development and Evaluation; HR: hazard ratio;MD: mean difference; RR: risk ratio

GRADE Working Group grades of evidence
High quality: Further research is very unlikely to change our confidence in the estimate of effect.
Moderate quality: Further research is likely to have an important impact on our confidence in the estimate of effect and may change the estimate.
Low quality: Further research is very likely to have an important impact on our confidence in the estimate of effect and is likely to change the estimate.
Very low quality: We are very uncertain about the estimate.

aQuality was rated as moderate because of unclear risk of bias for some domains in Marcus 2009 and Owen 2009, and because of the overall small number of studies conducted using aripiprazole in ASD.
bQuality of evidence for long‐term trials was rated as low because of high risk of attrition bias for incomplete outcome data in Findling 2014. Further research may have an important impact on our confidence in the estimate of effect and may change the estimate.

*A small number of studies have evaluated the use of aripiprazole for ASD. Only one study examined aripiprazole at a duration longer than eight weeks. Future trials of aripiprazole in children/adolescents with ASD are likely to impact the estimates found in this review.
