Oxford Comma

suggestion

"Posterior fossa ependymomas are the most common type of ependymoma, most commonly occurring in children. They are divided on the basis of DNA-methylation profiling into two groups, A and B."

Line 1:208 · Use the Oxford comma in 'groups, A and B'.

"Rarely extraneural metastases may occur, reported sites include: lymph nodes, mediastinum, lungs, pleura, diaphragmatic muscle, retroperitoneum, liver and bone ¹⁴."

Line 137:132 · Use the Oxford comma in 'retroperitoneum, liver and bone'.

Inline EG

suggestion

"T2* (e.g. SWI)"

Line 104:16 · Consider replacing a bracketed e.g. with an inline e.g. after a comma.
