To investigate the impact of revised diagnostic algorithm on presentation of multidrug-resistant tuberculosis cases at a referral centre in India.
Article in Journal of family medicine and primary care, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Introduction: A shift in policy has occurred with the introduction of molecular diagnostic tools for the upfront diagnosis of all cases of tuberculosis, including drug-resistant tuberculosis. The impact of this shift in policy on severity of disease was studied, and comparisons were drawn between the year 2015 and 2020. Study Type and Design: This was an observational study conducted between 2020 and 2021. Seventy patients of MDR-TB with or without additional drug resistance, hospitalized in the year 2015 and 2020, were studied. Results: The study reveals a substantial reduction in the median time from the onset of symptoms to diagnosis between 2015 and 2020. Specifically, the median duration decreased from 12 weeks in 2015 to 8 weeks in 2020. Moreover, we found that in 2015, all cases under study had a history of tuberculosis in comparison to 2020. Additionally, there was a higher incidence of anemia in 2015 compared to 2020. In the radiological examination, it was observed that in 2015, a higher frequency of cases exhibited cavitations, bronchiectasis, and fibrosis on chest X-rays compared to the findings in 2020. The mean cavity size in 2015 measured 6.73 cm, while in 2020, it averaged 4.06 cm. Additionally, we noticed a higher occurrence of significantly advanced cases in 2015 in contrast to 2020. Conclusion: The implementation of the new policy of upfront DST was noted to decrease the time required for diagnosis and bacterial load as ascertained from degree of sputum smear positivity, radiological lesions, and severity of anemia.
