There's some similar work out that analyses the impact on conference paper acceptance of having deanonymised arXiv versions of papers available before review. They look at ICLR papers for the last 2 years.
I've not read it in a lot of detail but it looks like there's a positive correlation between releasing papers and having them accepted. Not sure how they've controlled for confounders (you only release papers you're confident in the quality of on arXiv?) https://arxiv.org/pdf/2007.00177.pdf
