Overview of the twelve core subjects included in the 226 articles sought for retrieval (blue), the penultimate 35 articles (pink), and the 12 meta-analysed articles (yellow). Eighty-four articles (37%) contained in numbers, 107 articles contained no numerals (47%), 36 articles were not retrieved (16%), and 9 articles had no relevance to GPOC (4%). Of all 226 articles, the top-three subjects were privacy/security covered by 148 articles (65%), sharing by 78 (35%), and ownership by 48 articles (21%). Of the penultimate 35 articles, the top-three subjects were privacy covered by 22 articles (63%), sharing by 12 articles (34%), and movability by 6 articles (17%). Of the meta-analysed 12 articles the top-three subjects were privacy covered by 10 articles (83%), sharing by 6 articles (50%), and movability by 3 articles (25%). For the GPOC Word Cloud of the 100 commonest words, based on 38,000 words selected equally and representatively from all 190 eligible articles (out of 226 articles sought for retrieval), see Supplementary File 4 (S 4 ).
