Appendix 2.2 Coding framework 37
F.15 Was there concealment of study allocation or other key factors from those carrying out
measurement of outcome - if relevant?
Not applicable - e.g. analysis of existing data, qualitative
study.
F.15.1 Not applicable (please say why)
F.15.2 Yes (please specify)
F.15.3 No (please specify)
No - e.g. assessment of reading progress for dyslexic
pupils done by teacher who provided intervention.
Yes - e.g. researcher assessing pupil knowledge of drugs
- unaware of pupil allocation.
F.16 Which methods were used to analyse the data?
Please give details e.g. for in-depth interviews, how
were the data handled? Details of statistical analysis can
be given next.
F.16.1 Explicitly stated (please specify)
F.16.2 Implicit (please specify)
F.16.3 Not stated/unclear (please specify)
F.17 For evaluation studies that use prospective allocation please specify the basis on which data
analysis was carried out.
‘Intention to intervene’ means that data were analysed
on the basis of the original number of participants as
recruited into the different groups.
‘Intervention received’ means data were analysed on the
basis of the number of participants actually receiving
the intervention.
F.17.1 Not applicable (not an evaluation study with
prospective allocation)
F.17.2 ‘Intention to intervene’
F.17.3 ‘Intervention received’
F.17.4 Not stated/unclear (please specify)
F.18 Please comment on any other analytic or statistical issues, if relevant.
F.18.1 Details
Please comment on any other analytic or statistical
issues, if relevant.
Section G: Methods - Economic Analysis
G.1 What economic analysis was completed
Cost of intervention = Where total cost or cost per unit
of output only given
G.1.1 None
G.1.2 Cost of intervention only
G.1.3 Cost Benefit analysis
G.1.4 Cost effectiveness analysis
G.1.5 Cost Utility analysis
G.1.6 Coding is based on: Authors’ description
G.1.7 Coding is based on: Reviewers’ inference
Cost Benefit Analysis (CBA) = All costs and all benefits
of intervention are identified and weighed against each
other in common units (normally £)
Cost Effectiveness Analysis (CEA) = All costs and all
benefits identified in intervention and compared with
other possible interventions to achieve the same goal
- usually requires the same standard outcome measure
for example cost per n reduction in arrests
Cost Utility Analysis (CUA) = Can be either CBA or CEA but
in addition outcomes are converted into measure which
takes account of their quality or utility for example
Quality Adjusted Life Years (QALYS)
