Figure 1 Flow chart of review strategy and finally evaluated articles: The flow chart shows the systematic exclusion of search results towards the finally evaluated studies. The primary reasons for exclusion are mentioned including the number of concerned articles.

Figure 2 Distribution of included and excluded articles: Distribution of the 37 evaluated (green) and 159 excluded (red) studies of the search results ordered by their date of publication. Shaded fractions represent the 4 articles which were not available as full text version.

Figure 3 Shares of patients in the 37 evaluated studies with respect to the country of origin: The number of contributing studies is noted in brackets behind the country. Preponderance of United States is due to two reports of “mass X-ray evaluation” in the years 1977 and 1982. If these two are left out of consideration the median value of studied subjects in a paper is 212 (mean = 485).
