Diversity of Nontuberculous Mycobacteria in Kuwait: Rapid Identification and Differentiation of Mycobacterium Species by Multiplex PCR, INNO-LiPA Mycobacteria v2 Assay and PCR Sequencing of rDNA.
Article in Medical principles and practice : international journal of the Kuwait University, Health Science Centre, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled it.
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
objectiveNontuberculous mycobacteria (NTM) often cause disease that is clinically indistinguishable from tuberculosis. Specific identification is important as treatment varies according to Mycobacterium species causing the infection. This study used multiplex PCR (mPCR) assay for rapid differentiation of mycobacterial growth indicator tube 960 system (MGIT) cultures as Mycobacterium tuberculosis (MTB) or NTM together with INNO LiPA Mycobacteria v2 assay (LiPA) and/or PCR sequencing of rDNA for species-specific identification of selected MTB and all NTM isolates in Kuwait. MATERIALS AND
methodsDNA was extracted from MGIT cultures (n = 1,033) grown from 664 pulmonary and 369 extrapulmonary specimens from 1,033 suspected tuberculosis patients. mPCR was performed to differentiate MTB from NTM. LiPA was performed and results were interpreted according to kit instructions. rDNA was amplified and sequenced by using panmycobacterial primers.
resultsmPCR identified 979 isolates as MTB, 53 as NTM and 1 isolate as mixed culture. LiPA and/or PCR sequencing confirmed 112 of 979 selected isolates as MTB. Mixed culture contained M. tuberculosis and M. fortuitum. LiPA yielded 12 patterns and identified 10 species/species complexes among 47 NTM, M. kansasii + M. scrofulaceum in one culture and 5 isolates only at genus level. PCR sequencing yielded more specific identification for 22 isolates at the species/subspecies level.
conclusionsmPCR rapidly differentiated MTB from NTM. LiPA identified 44 of 52 NTM isolates at the species/species complex level and 2 mixed cultures. PCR sequencing yielded more specific identification at the species/subspecies level. Rapid differentiation as MTB or NTM by mPCR, followed by species-specific NTM identification by LiPA/PCR sequencing is suitable for the proper management of mycobacterial infections in Kuwait.
