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: This study was to determine risk factors and prognostic models for mortality in elderly patients with Stenotrophomonas maltophilia bacteremia. Objective: The aim of this study was to address this gap, we conducted this study to investigate the predictors of mortality and develop prognostic models for clinical practice. Methods: A retrospective study was conducted on 195 patients ≥ 60 years of age (median age 78 (68-85) years, 59.5 % male) at Thong Nhat National Teaching Hospital in Vietnam between January 1st, 2017 and December 31st, 2022. Patients who were treated in the hospital with the first positive blood culture for Stenotrophomonas maltophilia bacteremia were chosen for enrolment in this study. This investigation evaluated demographic and clinical characteristics and prognostic models for mortality. Results: The mortality rate was 37.4 %. Multivariate analysis showed that the significant independent risk factors for mortality were age (aOR, 1.08; 95 % CI, 1.04-1.13; p < 0.001), SOFA score (aOR, 1.38; 95 % CI, 1.14-1.68; p < 0.001), and APACHE II score (aOR, 1.10, 95 % CI, 1.03-1.17; p = 0.005). Bayesian model averaging method identified four clinically applicable models: age combined with both SOFA score and APACHE II score (AUC 0.884, R2 0.564), age combined SOFA score (AUC 0.874, R2 0.516), age combined APACHE II score (AUC 0.800, R2 0.340), SOFA score combined APACHE II (AUC 0.846, R2 0.507). Conclusion: Stenotrophomonas maltophilia bacteremia was severe in elderly patients with high mortality. Risk factors for mortality included age, SOFA, and APACHE II scores. The model comprising age, SOFA, and APACHE II scores has the best predictive ability. However, the model including age and SOFA score was also clinically valid and simple.
