I thought there was already common terminology for probability of side effects [0] Very common = greater than 1 in 10 Common = 1 in 100 to 1 in 10 Uncommon [formerly 'less commonly' in BNF publications] = 1 in 1000 to 1 in 100 Rare = 1 in 10 000 to 1 in 1000 Very rare = less than 1 in 10 000 Frequency not known = frequency is not defined by product literature or the side-effect has been reported from post-marketing surveillance data [0] https://bnf.nice.org.uk/medicines-guidance/adverse-reactions-to-drugs/ https://bnf.nice.org.uk/medicines-guidance/adverse-reactions...
