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

Direct identification (ID) and antimicrobial susceptibility testing (AST) of bacteria from positive blood cultures (BCs) are crucial for rapid optimization of therapy in sepsis. The FAST system purifies a Liquid Colony (LC) from BC broth within 25-35 min for downstream applications. We investigated the performance of the FAST system on BCs growing Gram-negative rods combined with mass spectrometry (MALDI-TOF-MS), the β-LACTA-test, and VITEK 2 AST from LC. VITEK 2 AST results were analyzed after 6 and 8 h, and their impact on empiric antibiotic therapy was examined. We included 119 BCs. MALDI-TOF-MS identified all pathogens correctly. The β-LACTA test detected hydrolyzation of third-generation cephalosporins (
