Letter to the editor: Methodological considerations for diagnostic test accuracy meta-analyses

• This correspondence discusses key methodological considerations specific to diagnostic test accuracy meta-analyses. • It explains why intervention-style heterogeneity metrics and separate pooling mislead in DTA reviews. • It highlights the need for HSROC plots with confidence and prediction regions. • It calls for transparent handling of sparse data and appropriate assessment of heterogeneity and bias.
