Funding sources: none.

Conflicts of interest: none declared.

Dear Editor, I read with interest the 2017 article by Gómez‐García and colleagues titled ‘Systematic reviews and meta‐analyses on psoriasis: role of funding sources, conflict of interest and bibliometric indices as predictors of methodological quality’, published in the BJD.1

This study makes a very important point about the influence of funding sources and conflicts of interest on the methodological quality of systematic reviews. However, I have some concerns about the search strategy used to find systematic reviews for this analysis. There seems to be a recent trend for more overviews of systematic reviews or so‐called umbrella reviews to be published, and I have observed that many share the same issues in the search strategies used. This study used only the search terms ‘meta‐analysis’ and ‘systematic review’ to find systematic reviews, and, as a result, some relevant systematic reviews would not be found in the searches.
