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
BACKGROUND &
objectivesMultiple drug resistance (MDR) among Mycobacterium tuberculosis poses a serious therapeutic problem. Early detection of MDR can be valuable but the conventional drug susceptibility tests take 4-6 wk time after the laboratory isolation of M. tuberculosis. The bacterial phage assay has been reported as a rapid tool for rifampicin susceptibility testing of tubercle bacilli using the suspension of isolated cultures. The present study was aimed to set up a phage assay for testing drug susceptibility to isoniazid (INH), rifampicin, ethambutol, streptomycin and ciprofloxacin in M. tuberculosis isolates.
methodsMueller-Hinton broth instead of Middle Brook 7H9 broth was used to make it more economical. The phage assay was compared with the proportion method using 100 M. tuberculosis isolates from pulmonery TB cases. Phage assay results were available in 48 h for rifampicin and streptomycin while 72 h required for INH, ethambutol and ciprofloxacin. The assay was compared with gold standard proportion method. Interpretation of the results was easy and clear.
resultsIn the present study, sensitivity and specificity of the phage assay when compared to proportion method were in the range of 97 to 100 per cent for all the drugs except for ciprofloxacin for which it was 93 and 96 per cent, respectively. INTERPRETATION &
conclusionsThe phage assay was economic, easy to perform and rapid for the detection of drug resistance in M. tuberculosis isolates with no requirement of expensive equipment. It is within the reach of microbiology laboratories in developing countries having high loads of tuberculosis.
