Since initial publication of these abstracts there are some changes and additions required as follows:
doi: 10.1136/jim-2019-WMRC.135
The author order was listed incorrectly with S Ravaie as the third author. S Ravaei should have been listed as the first author. The author list should therefore be S Ravaei, K Ludwig, H Kornblum.
doi: 10.1136/jim-2019-WMRC.464
This abstract has been retracted. The online version of the abstract supplement and author index have been updated to reflect the changes.
