Not GP, but I'd prefer '34' over '94%'. (Especially since the latter was parenthesised - I'd remove the parenthetical before anything else.)

(Or just 94%, and then have people say 'but N= only 36!'.)

Percentages for small numbers, in particular below 100, are just annoying and often designed to mislead. (Though I'm not suggesting that here, it's standard in medicine if not other fields.)
