Cascade of deoxyribozymes for the colorimetric analysis of drug resistance in Mycobacterium tuberculosis.
Article in Biosensors & bioelectronics, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
A visual cascade detection system has been applied to the detection and analysis of drug-resistance profile of Mycobacterium tuberculosis complex (MTC), a causative agent of tuberculosis. The cascade system utilizes highly selective split RNA-cleaving deoxyribozyme (sDz) sensors. When activated by a complementary nucleic acid, sDz releases the peroxidase-like deoxyribozyme apoenzyme, which, in complex with a hemin cofactor, catalyzes the color change of the sample's solution. The excellent selectivity of the cascade has allowed for the detection of point mutations in the sequences of the MTC rpoB, katG, and gyrA genes, which are responsible for resistance to rifampin, isoniazid, and fluoroquinolone, respectively. When combined with isothermal nucleic acid sequence based amplification (NASBA), the assay was able to detect amplicons of 16S rRNA and katG mRNA generated from 0.1 pg and 10 pg total RNA taken for NASBA, respectively, in less than 2 h, producing a signal detectable with the naked eye. The proposed assay may become a prototype for point-of-care diagnosis of drug resistant bacteria with visual signal output.
