Fig. 5From: Diagnostic accuracy of in-house real-time PCR assay for Mycobacterium tuberculosis: a systematic review and meta-analysisA Deeks’ funnel plot assessment test evaluated the potential publication bias for in-house RT-PCR assays. The plot shows the symmetric distribution of the log of diagnostic odds ratios against the inverse root of effective sample sizes (ESS), indicating the absence of any publication biasBack to article page
