Notes. The last row of each subtable gives the average value weighted by the inverse variance. The blanks indicate that the analysis did not converge (see Sect. 5.1).
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
