Open access, and what it is worth here

Open-access share0.9%

There are too few years in which Parkinsonism and Related Disorders published both open and paywalled articles in quantity to compare the two without the comparison turning into a comparison of article ages.
Parkinsonism and Related Disorders open access
This chart shows the share of Parkinsonism and Related Disorders's peer-reviewed articles published under an open licence, by year, with the percentile among comparable entities. The licence is read from the article itself, so the denominator is the articles whose licence could be established — an article carrying no licence statement is left out of both sides rather than counted as closed. A year appears only where at least 10 articles carry a readable licence, which is why the series begins where open licensing does rather than at the start of the record.
