Determination of the activity of standard anti-tuberculosis drugs against intramacrophage Mycobacterium tuberculosis, in vitro: MGIT 960 as a viable alternative for BACTEC 460.

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
BACTEC 460 has now been phased out, so the search for an alternative is imperative. We have determined the activity of standard anti-tuberculosis drugs against intramacrophage Mycobacterium tuberculosis, in vitro, by using BACTEC 460 and MGIT 960 methods. The minimum inhibitory concentrations of isoniazid, rifampicin, ethambutol and streptomycin against intracellular M. tuberculosis H37Rv were found to be 0.2, 0.8, 8.0, and 5.0 μg/mL, respectively, by both methods. These results show a significant (p<0.001) concordance between minimum inhibitory concentrations obtained by these two different methods. MGIT 960 system uses a robust florescence quenching-based oxygen sensor, requires no radioisotope, is safe, and relatively easy to operate. Apparently, this is the first report wherein MGIT 960 has been validated for anti-tubercular susceptibility testing against intracellular M. tuberculosis H37Rv. Our preliminary data thus clearly demonstrate that the MGIT 960 method can be considered as a promising alternative to BACTEC 460 method.
