Boxplots of Ct values from paired URS and SS tested by Sansure quantitative PCR in study of diagnostic accuracy of 3 mpox lateral flow assays for antigen detection, Democratic Republic of the Congo (DRC) and United Kingdom. A) DRC, n = 14; B) United Kingdom, n = 9. Horizontal lines within boxes indicate medians, box tops and bottoms indicate interquartile range, and whiskers indicate maximum and minimum values. Ct values were significantly higher (p<0.05) in the URS group than in the SS group in the DRC cohort. Ct, cycle threshold; SS, skin lesion samples; URS, upper respiratory specimens.
