Polymorphic exact tandem repeat A (PETRA): a newly defined lineage of mycobacterium tuberculosis in israel originating predominantly in Sub-Saharan Africa.
Article in Journal of clinical microbiology, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
As part of the Israel National Program for Prevention and Control of Tuberculosis, the molecular epidemiology of new tuberculosis cases is monitored. Prospective screening showed that about 20% of all new cases of culture-positive tuberculosis (43 of 222) in Israel in the year 2008 were caused by certain Mycobacterium tuberculosis strains of the central Asian (CAS) spoligotype lineage. The identity and similarity of these strains by mycobacterial interspersed repetitive-unit-variable-number tandem-repeat (MIRU-VNTR) typing form a lineage we call PETRA for polymorphic at locus ETR A. The name PETRA was given to 79 strains we have found since the year 2000, because the largest number of strains with MIRU-VNTR profiles identical other than at locus A formed three groups, including 5 of 10 strains that had deleted the ETR A region from their genomes. No PETRA strain was found to be multiple drug resistant (resistant to both isoniazid and rifampin [rifampicin]). Most patients (75% [58 of 77 patients of known origin]) infected with PETRA were of sub-Saharan African origins. The genotypes associated with the 79 PETRA lineage strains presented in this paper suggest that the PETRA lineage is a large, major contributor to new tuberculosis cases in Israel.
