Study selection:
Systematic search of databases retrieved 3502 articles. By removing
duplicate papers, 2199 articles remained for reading title and abstract.
After reading titles and abstracts, 2169 of them were excluded; 30 RCTs
remained for reading full text. Seven articles were excluded due to
following reasons: non-English article (n=1), using other nutrients
beside soy intervention (n=5), not reporting CRP unit (n=1)
(Figure 1 ). Therefore, 23 papers were eligible for this
systematic review (24-36,
46-55). Since 4 articles
(28, 32,
50, 55)
did not report enough data for meta-analysis, 19 articles were included
in meta-analysis (24-27,
29-31,
33-36,
46-49,
51-54). (Table 1 ).
