Therefore, it would be worthwhile to examine in future studies whether it is better to validate the TTO against individualized measures of personal preferences, such as the SEIQOL [ 19, 20] or MACTAR [ 21].
The choice of tools used in research was influenced by whether it had been validated within palliative care (29/40), whether they had access to the tool (25/40) and the time needed for completion (23/40).
The data extracted for each article were: first author's last name, publication year, country where the study was conducted, the study name, follow-up period, sample size, gender, age, number of cases, dietary assessment method (type, number of food items, and whether it had been validated), type of fruit and/or vegetable, amount of intake, RRs and 95% CIs and adjustment variables.
Thus, when deciding whether to include knowledge within a Process Description, it is useful to ask whether those particular experts are in a position to validate it and, if so, whether it is sensible for it to be validated as part of a description of that particular process, or whether it should be decoupled and examined separately.
Here we describe whether diagnostic research is validated, which technique is used, and to what extent the validation study results differ from the original.
Although the HbA1c level in blood is now an accepted measure for diagnosis of diabetes in the US, it is unclear whether it was also validated for the Bangladeshi population.
This commentary elaborates on how such a measure of severity should be validated to determine whether it is appropriate for practical use.
The modified U-system includes various approximations so that it is necessary to validate whether it is practicability and conformable to experimental data.
