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

A pyrosequencing-based method for the rapid detection of isoniazid (INH) and rifampin (RIF) resistance in Mycobacterium tuberculosis was evaluated in clinical practice. The method can detect the INH resistance-causing katG315 mutation, and all mutations in the RIF resistance-determining rpoB core region, in less than 6 h from cultured isolates. The method was first validated with 42 isolates, and was subsequently prospectively evaluated with 91 isolates, including clinical isolates and external quality control assessment strains, over a period of 2.5 years. The pyrosequencing results of clinical isolates were available, on average, 19 days earlier (median 19 days; range 3-43 days) than conventional susceptibility testing results. The composite data showed that the sensitivity of pyrosequencing for detecting resistance correctly was 66.7% for INH and 97.4% for RIF. The specificity of pyrosequencing was 100% for both drugs. Acceptable sensitivity for detecting resistance and the rapidness of pyrosequencing make it a valuable tool in the clinical setting.
