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
Rapid identification of bacterial species from patient samples is crucial for clinical decision-making. In severe infections, such as bloodstream infections, the early start of an effective treatment is directly associated with reduced mortality rates. Current rapid species identification methods, such as matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) or multiplex PCR, require specialized hardware and extensive technical support that prevents application in resource-limited settings. Here, we present a staining and imaging procedure for bacterial smears using fluorescent dyes directed against intracellular structures and cell wall components. Data on relevant features were extracted from segmented images and used to train a machine learning (ML) model for species classification. The method was tested on clinical isolates from 126 patients. For the seven most common bacteria, the classification performance, indicated by area under the receiver operating characteristic (ROC) curve, ranged from 0.8 (
