The lack of a period effect in the current French analysis, where data categorisation differed from that of previous studies, favoured the artefactual nature of the period effect.
Bedson and colleagues, using GPs in a consensus exercise, derived a hierarchical analgesic categorisation where all analgesic formulations were categorised into six groups according to equipotency levels when treating varying levels of perceived pain as shown in Figure 1 [ 13].
This is illustrated by Virfam prophage categorisation, where 22 of 23 prophages in clades 2, 3, and 4 were categorised as Type 1, Cluster 3 Siphoviridae with high similarity to phages D3, HK97 and HK022 (the exception being Mcat28, which was categorised as a Type 1, Cluster 1 Siphoviridae).
This is definitely not remotely like my university's library, where the Dewey categorisation system still reigns supreme.
The study therefore used a standardised recording form with descriptors and categorisation where possible, and differentiation of critical cases was focused on differences on clinical parameters.
Correlations were interpreted using Dancey and Reidy's categorisation where ±1 indicates a perfect correlation; ±0.7 - ±0.9 indicates a strong or high correlation; ±0.4 - ±0.6 indicates a moderate correlation; ±0.1 - ±0.3 indicates a low or weak correlation and 0 indicates no correlation [ 13].
[So] while 90% of our books don't have boy or girl in the title … we are going to continue with these categorisations where we think they are necessary, with these sensitivities in mind".
Present approach incorporates the human knowledge to a hierarchical categorisation process, where the features of the three natures are independently categorised.
5 In clinical practice, this will be particularly important near the threshold for diagnosis, where most errors in categorisation will occur if ambulatory monitoring is not used.
