The questionnaire discriminated well between clinically distinct subgroups of patients both before and after treatment lending support to its convergent and clinical validity.
Additional ongoing studies of the clinical validity of the PAM50 gene expression signature for chemosensitivity prediction [ 34- 36] could, if confirmed, be considered clinically actionable given the demonstrated analytical validity of this test.
A fine balance must be struck to ensure these apps can be clinically validated within a reasonable time frame, whilst maintaining validity in the scientific approach and the evidence-base that is generated.
Clinically, the validity of scoring systems has been evaluated by comparing to another well-accepted system or examining serial scores which correspond to the change of neurological function [ 48– 53] in human medicine.
However before this is test is embraced clinically, the reliability, validity, diagnostic accuracy and clinical utility needs to be confirmed.
Second, the cut-off criteria for most studies were set without clinically established diagnostic validity.
Further study, however, will be required to clinically confirm the validity of the correlations between BMD loss and reduced muscle strength determined in this study before widely applicable clinical guidelines can be generated.
