Table 5 Overview of the sample-level PRECIS-2 scores per domain. The last column of the table displays the number of times the individual domains could not be graded, either because they were not applicable to the studies in question (e.g. flexibility in terms of adherence cannot be assessed for trials of surgical techniques, as these are single-application interventions), or due to a lack of relevant information provided in the source documents that were consulted for each PCT
