Comparison of Accelerate PhenoTest BC Kit and MALDI-TOF MS/VITEK 2 System for the rapid identification and antimicrobial susceptibility testing of gram-negative bacilli causing bloodstream infections.

The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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.
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
Background: Our laboratory uses matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI) and the VITEK 2 system (DV2) directly from positive blood cultures (BC) for organism identification (ID) and antimicrobial susceptibility testing (AST). Our objective was to compare direct MALDI-DV2 with a commercial BC ID-AST platform, the Accelerate Pheno system (AXDX), in the ID-AST of clinical and seeded BC positive for gram-negative bacilli (GNB). Methods: BC positive for GNB were collected over a 3-mo period and tested using AXDX and direct MALDI-DV2 and compared with conventional methods. A subset of sterile BC were seeded with multi-drug-resistant GNB. Results: Twenty-nine clinical samples and 35 seeded samples were analyzed. Direct MALDI had a higher ID failure rate (31.0%) than AXDX (3.4%; Conclusions: Direct MALDI-DV2 and AXDX both had high agreement for clinical samples, but direct MALDI-DV2 had higher agreement when challenged with MDR GNB.
