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 category (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 large categories, and cases with ≥4 acquisitions were defined as stratum 4 for the small category.
cWald test (P<.05).
dP<.001.
eDoctoral degree conferred by submitting a doctoral thesis and passing its examination. We used this as a control variable and conducted an analysis by assigning a value of 0 for a regular degree and 1 for a doctorate obtained by thesis.
fInteraction among researchers in the same position was expressed as the number of researchers who made the participant a project member.
