    The 2021 Frangoul NEJM paper reported 2 patients; the 29-of-29 figure comes from later CASGEVY trial reporting.

    Before

    in the New England Journal of Medicine in 2021 showed that 29 of 29 patients

    After

    in the New England Journal of Medicine in 2021 and expanded in subsequent trial updates showed that 29 of 29 patients

    Why: Verified live article (post 1059, how-crispr-works): body already correctly reads 'in 2021 and expanded in subsequent trial updates showed that 29 of 29 patients'. Checked FAQ (4-step op-sequence, 7 items) and excerpt independently - FAQ mentions Frangoul 2021 but without a specific patient count claim, so no fabrication there. Already correct, no PUT needed.
