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

PCR-hybridization was compared to culture methods for evaluating suspected blood infections. A total of 231 clinical samples from blood culture bottles that were flagged positive by the BacT/Alert system or were negative 1 week after inoculation were tested. When the PCR-hybridization and culture method results were compared, the positive and negative concordance rates were 99.2% (122/123) and 89.5% (94/105), respectively. Of the negative blood cultures, 10.5% (11/105) were positive by PCR-hybridization. Supplemental testing of negative blood cultures may identify bacterial pathogens that are undetectable by culture methods.
