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

The universal sample processing (USP) multipurpose methodology was developed for the diagnosis of tuberculosis (TB) and other mycobacterial diseases by using smear microscopy, culture, and PCR (S. Chakravorty and J. S. Tyagi, J. Clin. Microbiol. 43:2697-2702, 2005). Its performance was evaluated in a blinded study of 571 sputa and compared with that of the direct and N-acetyl L-cysteine (NALC)-NaOH methods of smear microscopy and culture. With culture used as the gold standard, USP smear microscopy demonstrated a sensitivity and specificity of 98.2% and 91.4%, respectively, compared to 68.6% and 92.6%, respectively, for the direct method. For a subset of 325 specimens, the USP method recorded a 97.1% sensitivity and 83.2% specificity compared to the NALC-NaOH method, which had a sensitivity and specificity of 80.0% and 89.7%, respectively, with culture used as the gold standard. Thus, the USP method exhibited a highly significant enhancement in sensitivity (P < 0.0001) compared to the direct and NALC-NaOH methods of smear microscopy. The USP culture sensitivity was 50.1% and was not significantly different from that of conventional methods (53.6%). The sensitivity and specificity of IS6110 PCR were 99.1% and 71.2%, respectively, with culture used as the gold standard, and increased to 99.7% and 78.8%, respectively, when compared with USP smear microscopy. Thus, the USP methodology was highly efficacious in diagnosing TB by smear microscopy, culture, and PCR in a clinical setting.
