1 · What the graph read from 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.

2 · The registry

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: Bedaquiline (BDQ) resistance is a significant threat to tuberculosis (TB) control efforts, particularly in areas with a high burden of multidrug-resistant (MDR) and extensively drug-resistant (XDR) tuberculosis, such as South Africa. Determining the minimum inhibitory concentration (MIC) of BDQ and identifying the associated resistance-conferring mutations are critical for understanding resistance patterns and guiding therapeutic decisions. This study investigated BDQ resistance in Method: This study is a cross-sectional study including 147 drug-resistant (DR-TB) isolates obtained from the Polokwane laboratory, Limpopo province, South Africa. The study used phenotypic MIC drug susceptibility testing and whole-genome sequencing (WGS) to investigate BDQ susceptibility patterns. MIC determination and genetic analysis were performed on all isolates with an MIC of >1 μg/mL and a subset of those with an MIC of <1 μg/mL as a control for sequencing. Results: Of the 147 DR-TB isolates included, 128 (87.1%) had an MIC of ≤1 μg/mL (susceptible), while 19 (12.9%) had an MIC of >1 μg/mL (resistant). Whole-genome sequencing revealed that mutations in Conclusion: In this study, BDQ resistance was primarily driven by Rv0678 mutations. As BDQ is one of the few potent drugs available for treating DR-TB, there is a critical need for early detection and continuous surveillance to prevent the spread of resistance.
