  1. 01HumanObservational studySafety outcome

    In FDA adverse event reports, Wegovy showed the strongest signal for ischaemic optic neuropathy (reporting odds ratio 74.89).

    In plain wordsIn FDA safety reports, Wegovy was linked to the strongest signal for an eye nerve problem. A report signal does not prove cause.
