Their guidance indicates that those who conduct a TTO study should follow the measurement and valuation of health (MVH) protocol developed in the UK EQ-5D valuation studies, based on the desire to enhance comparability with studies that derive utilities from the EQ-5D [ 9].
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.
For external validation, they should describe the populations that are used for the validation, particularly the comparability with the population that was used to derive the risk model.
To establish comparability with other research that used a participant-defined definition of breakfast, we compared the diet-diary derived breakfast consumption with a participant-diet-diary derivedreakfast question.
The cost-effectiveness ratio is presented with and without the peer educator economic costs because of the uncertainty around these estimates and to aid comparability with other studies that do not include these costs.
However, there were some limitations: (i) To achieve comparability, sampling was both clustered (by district) and stratified by geographical location of schools for both I-salt and goitre palpation in an attempt to improve the comparability with 1980s surveys that used this procedure [ 6].
Then, we investigated the comparability of our study with that of Cohen (2009).
The comparability of our results with that of NDHS with regards to antenatal care use, for example, suggests that such bias is not likely to have affected our findings in any significant way.
We summed the frequency counts for these estimates and calculated odds ratios for Black and White groups, respectively, to allow comparability with the other studies that examined aggregated ethnic groupings.
Our choice of PCV9 for the base-case analysis was primarily motivated by the availability of local clinical trial data for PCV9 [ 8, 9] and comparability with the previous study that evaluated the cost-effectiveness of PCV9 [ 24].
