Appendix 1: Data review classification results
This section provides an overview of the data classification that was undertaken. These are divided into economic and non-economic reports.
A total of 95 documents were reviewed, of these 54 contained evaluation data. Eight duplicates were identified. See Table A1.1 for a summary of these.
Table A1.1: Number and type of documents submitted to JE for analysis within each workstream
|Total number of documents containing evaluation data||28||7||13||7|
|Total number of documents containing background information||25||0||3||3|
|Total number of documents reviewed||59||7||18||10|
Of the evaluations, half related to HMHM, 22% to Telecare and 13% each to DP and VC. See Figure A1.1 for a breakdown across the workstreams.
Figure A1.1: Reports containing evaluation data
After the initial classification, we began the analysis of each of the documents containing evaluation data. These were classified by the type of data they contained. Table A1.2 gives a breakdown of the data type by workstream. Note that mixed method reports were counted twice ( i.e. containing both quantitative and qualitative data), hence the total number presented here is higher than the total number of reports included.
Table A1.2: Breakdown of qualitative and quantitative data by workstream
A total of 10 reports containing economic or cost data were submitted to Just Economics for review across the four workstreams in September 2017 (see Table A1.3).  Reports that contained only project cost data, but no economic analysis of benefits were excluded from the review, as were forecasted cost-benefit analysis (see Box 1 for a discussion of the main findings of these).

Table A1.4 summarises the main features of the studies.

|Valuation of outcomes to multiple stakeholder||0||0||0||1||1|
|Discounting of benefits (if applicable)||0||3||0||1||3|
