Nkurunungi and colleagues found in their cross-sectional study conducted on 907 children screened for LTBI in a high prevalence African setting that T-SPOT.TB results were unstable over a three-week follow-up interval, and that TST compares poorly with T-SPOT.TB, making the categorisation of children as TB-infected or TB-uninfected difficult [ 60].
Lotz et al. [5] have made a categorisation of errors based on stages in the cause effect chain (Table 2).
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.
Individually categorising these values per time step makes, on the one hand, the categorisation task more difficult but, on the other hand, delivers a categorisation without making prior assumptions about the temporal characteristic.
In the 21st century much of the most interesting work being made completely defies categorisation.
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.
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).
As previously discussed, the nature of the Together for Short Lives/RCPCH categorisation makes it more difficult to decide clearly on life-limiting conditions, since simply by being so young, the chance of surviving to adulthood is smaller than in childhood itself.
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.
Increasing treatment options in endometrial cancer make accurate histopathological categorisation and molecular profiling essential, although predictive factors related to the EGFR/PI3K pathways have not been validated sufficiently for routine use.
