aThe number of projects obtained by the participants as principal investigators was used as the dependent variable. The term large indicates projects from the Grant-in-Aid for Scientific Research (S) and Grant-in-Aid for Specially Promoted Research, which are considered large categories. Similarly, the term small indicates the Grant-in-Aid for Scientific Research (C), which is considered the smallest category.
bNumber of projects obtained. Cases with no corresponding acquisitions were designated as stratum 0 and used as a reference. Cases with ≥2 corresponding acquisitions were defined as stratum 2 for the large categories, and cases with ≥4 acquisitions were defined as stratum 4 for the small category.
cWald test (P<.05).
dP<.05.
eP<.01.
fNo results were output by XLSTAT software for this stratum.
gP<.001.
