Although self-report measures are viewed as the most reliable and valid assessments of subjective craving, they are still subject to such limitations as individuals' unwillingness or inability to report on internal processes [ 79, 80].
To choose the most valid statistical methods for research synthesis, an appropriate assessment of primary studies included in evidence network is required.
A review of the evidence is needed on which of these methods and instruments is most valid, reliable and responsive which, in turn, reduces assessment burden and redundancy of similar outcome measures.
A definitive answer to the question of which assessment of motor function is the most valid, reliable and responsive in CTS continues to elude us.
