Phil Davis has published interesting results on the question whether

In my view, Phil has convincingly shown that, at least for the
journals and the time intervals he studied, there is no meaningful
OA citation advantage.
I don't understand Ludo Waltman's point, since this is exactly what I said:
SH:
Phil Davis's dissertation results are welcome and interesting, and
include some good theoretical insights, but insofar as the OA
Citation Advantage is concerned, the empirical findings turn out to
be just a failure to replicate the OA Citation Advantage in that
particular sample and time-span... it is most definitely not a
demonstration that the OA Advantage is an artifact of
self-selection, since there is no control group demonstrating the
presence of the citation advantage with self-selected OA and the
absence of the citation advantage with randomized OA across the same
sample and time-span: There is simply the failure to detect any
citation advantage at all.
