It was possible to make the same categorisation by immunohistochemistry (IHC) using markers aimed at luminal, Her2, and basal-like features (Makretsov et al, 2004).
The number of critical non-presented words recalled (false memories), the number of critical non-presented words recognised (false memories), and the number of errors made on the categorisation test were calculated for each individual.
Owing to the large number of references identified, and the need to read abstracts and full articles for further selection and categorisation, we made the decision to focus on articles published between January 2008 and September 2010.
Rules of thumb with two different purposes have been identified: to simplify categorisation of the problem to a disease and to make the consultation patient-centred [ 16, 17].
The original categorisation of the data would have created 256 such subgroups and made the interpretation too complex.
Our findings show a trade-off between word categorisation ability and semantic false memory susceptibility, so that individuals that make more errors on the false memory test make fewer errors on the categorisation test, and vice versa.
Firstly, forming and closing practices were quite unstable in the time period with regard to both number of doctors and number of patients, making categorisation quite difficult, and secondly, we hypothesised that forming and closing practices could confound our results in favour of larger practices.
Following the categorisation made in [3, 4], majority of the methods can be viewed to be either segment and classify or separate and detect approaches.
PB participated in the data-collection, the Delphi rounds, made substantial contributions to the categorisation and also gave comments on the writing of the manuscript.
For example, while inpainting of specular highlights may help in detecting polyps (both for human observers and algorithms) it could make their categorisation more difficult, as it alters the pit-pattern of the polyp in the vicinity of the specular highlight.
