Therefore, adopting international guidelines for defining TBI's will improve the quality of the registry and facilitate comparability with other literature.
The use of QALYs as their main outcome is justified with recommendations of regulatory bodies or with better comparability with other studies.
In order to achieve a better comparability with other scales of the questionnaire, the originally three-point-scale was transformed into a five-point scale ('never' (1) to 'always' (5)).
Classification of functioning, disability and health applied to headache disorders allows comparability with other health conditions as well as evaluation of the role of the environment as a cause of disability amongst people with headache.
One of the main advantages of analysing accessibility levels and its determinants using index number theory is that this type of approach allows comparability with other studies that may use the same methodology in other places and times.
In order to arrive at total global emissions estimates and provide comparability with other estimates, global net LULUCF emissions were harmonized to historical GHG emissions estimates [20] through the use of a harmonization factor that stays constant over time.
In order to provide global coverage of net LULUCF emissions and comparability with other estimates, a harmonization factor was used to cover the net LULUCF emissions for Parties not analyzed in this study.
Therefore, to avoid bias through incomplete accounting, and to ensure consistency and comparability with other GHG sectors, the full impact of policy-based changes in harvest beyond the continuation of management practices should be accounted for in the LULUCF sector.
Age-standardization was used to improve comparability with other studies and generalizability to other populations.
All additional outcomes were pre-specified before analysis; some were included in a separate analysis plan because we felt they were clinically important indicators, whereas others were included in order to facilitate comparability with other IPTi studies.
For comparability with other studies, we grouped that study into the category 'activity duration'.
