Readers need complete, transparent information and failure to provide this will short circuit critical appraisal, assessment of external validity and impact decisions on whether, for instance, a surgeon should change their practice.
This study was aimed to examine the differences and agreements between these three weights, psychometric properties including test-retest reliability, convergent and known-groups validity, and the impact of differences in the EQ-5D scores on the outcome of cost-utility analysis in Thai people.
Decisions about interim analysis and early stopping of clinical trials, as based on recommendations of Data Monitoring Committees (DMCs), have far reaching consequences for the scientific validity and clinical impact of a trial.
There are few reports on efficiency, validity and the impact of item non-response, from developing countries.
The aim of this study was to translate and evaluate the reliability and validity of the Persian versions of Impact of Burn Specific Pain Anxiety scale (BSPAS) and Impact of Event Scale (IES).
First, the wide range and significance of impacts captured in our study suggest that a clearer conceptualisation and standardisation of impact measures is required in order to increase the validity and reliability of impact assessment.
We did not attempt to evaluate the justification of the focus in individual studies, nor did we attempt to assess the validity or impact of individual articles.
Considering factors such as complementarity, landscape heterogeneity, functional diversity, and the rigor of vegetation surveys may also help improve the validity, and thus the impact, of coffee certification programs designed with the goal of conserving tropical montane biodiversity.
Similarly, the importance of incorporating patients' perspectives to establish domain and content validity of the impact of stroke on QOL using qualitative research, either by asking patients directly or by using the evidence base has also been recognised [ 9].
