Summary of Findings The authors of the letter highlight that a systematic review of PD-L1 expression for survival in head and neck squamous cell carcinoma published in 2018 did not provide a protocol or register with PRSOPERO to enable the methods of the review to be replicated and that exclusion criteria were applied to the clinical topic which limited the applicability of the results.
