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

backgroundBloodstream infections (BSI) related mortality rates are increasing worldwide making it a medical emergency. This study has evaluated a new method for direct detection of pathogens and to perform direct antimicrobial susceptibility testing from the positive flagged blood culture. Early diagnosis and prompt treatment with appropriate antibiotics is the utmost need.

methodA 30-minute protocol for pellet formation was developed using the positive blood culture bottle broth by triton X, SDS and saponin method for direct identification of pathogens. Clinical blood culture samples from patients, positive for Gram-negative bacteria, were included in the study (160 for direct identification and 250 for direct antimicrobial susceptibility testing). We compared results with routine method.

resultsThe agreement of Triton X, SDS and saponin direct identification method compared to the conventional method was 96.2%, 91.8% and 90% respectively. A total of 960 pathogen and antimicrobial agent combinations were tested, 99.8% antimicrobial sensitivity testing results by direct method showed categorical agreement with the standard routine disc diffusion method.

conclusionOverall, the newer method of direct microbial identification and antibiotic sensitivity testing is both time and cost effective.
