Summary of Findings	From a letter highlighting concerns in the conduct of a systematic review on ticks infected with Crimean-Congo haemorrhagic fever virus, published in 2022. The concerns raised in this letter relate to: the literature search, data extraction, and statistical analysis, reportedly carried out by a single author; lack of information regarding search time points, language restrictions, the search strategy, or the inclusion or exclusion criteria. The letter authors report that there is no information about the quality assessment of the included studies. There are reportedly issues with the assessment of heterogeneity and the authors highlight that neither sensitivity nor a meta-regression analysis was conducted to determine whether the confounding variable affected the overall estimates. Finally neither publication bias nor other limitations of review were mentioned by the review authors.
