What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Leber hereditary optic neuropathy (LHON) is a degenerative disease of the optic nerve associated with one of three mitochondrial DNA (mtDNA) m.3460G>A, m.11778G>A and m.14484T>C mutations. Although several procedures are available to genotype these mutations, quantitative approaches with rapid, low-cost and easy to handle advantages for three LHON mtDNA mutations are rarely reported. Here, we firstly developed a "one-step" tetra-primer amplification-refractory mutation system (T-ARMS) PCR for qualitative genotyping of three LHON mtDNA mutations. Subsequently, we established single, duplex and triplex TaqMan MGB probe-based fluorescence quantitative PCR (qPCR) assays to perform both qualitative and quantitative analyses of three LHON mtDNA mutations. Standard curves based on tenfold diluted plasmid standard exhibited high specificity and sensitivity, stable repeatability and reliable detectable ability of TaqMan probe qPCR assays without cross-reactivity upon probes combination. Moreover, by comparing with SYBR Green qPCR, we further validated the feasibility of the triplex-probe qPCR assay for the quantitative detection of mtDNA copy number in blood samples. In conclusion, our study describes a rapid, low-cost, easy to-handle, and high-throughput TaqMan-MGB probe qPCR assay to perform both qualitative and quantitative analysis of three primary LHON mtDNA mutations, offering a promising approach for genetic screening and testing of LHON mutations.
