As such, we aim to examine the empirical evidence quantifying the extent of bias associated with methodological and non-methodological characteristics in oral health RCTs.
Research themes and methodological characteristics are analysed in order to establish an evidence base in Arctic shipping literature.
Both biological and methodological characteristics were examined in an attempt to explain the possible causes of heterogeneity (i.e., the possible causes modifying the outcome) among the studies.
The geographic distribution of these studies by country and the number of studies published per year are shown in Fig. 2. The methodological characteristics of the studies included in the review are summarized in Table 2.
Each study was examined to identify the methodological characteristics that were followed in estimating CAP; these methodological aspects are summarized in Table 2. Finally, Table 3 summarizes in detail the estimated total societal costs and components.
However, we assume that NI trials retrieved from PubMed do not have different methodological characteristics than NI trials in other databases, so we do not think that this influenced our results.
This descriptive analysis provides information on the extent of evidence synthesis on child-relevant topics as well as variation in methodological characteristics and rigour across the reviews.
Randomisation and allocation concealment have been extensively investigated in the medical literature as key methodological characteristics of randomised controlled trials (RCTs) in medical research.
Methodological characteristics and quality are presented in Table 1.
We also perceived differences in the methodological characteristics of the networks, such as definitions and registration rules used.
