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
BACKGROUNDAccurate, fully automated systems may increase efficiency of healthcare-associated infections (HAI) surveillance.AIMWe aimed to validate the performance of a fully automated surveillance system for central-line-associated bloodstream infections (CLABSI) in critically ill patients in Switzerland.METHODSWe conducted a multicentre retrospective study across six secondary and tertiary care hospital networks' intensive care units (ICU). A centrally hosted, fully automated algorithm was implemented to detect catheter-related bloodstream infections (CRBSI), CLABSI and ICU-onset bloodstream infections (ICU-BSI). Algorithm performance was validated against an anonymised manual review of random samples of positive blood cultures. Incidence data were computed for each hospital.RESULTSFrom January 2022 to December 2023, we analysed 131,166 patient days, 108,719 catheter days and 7,832 positive blood cultures from 1,931 ICU patients. Median age was 65 years (interquartile range (IQR): 53-73), 458 (23.7%) were female. For CLABSI and CRBSI, the algorithm demonstrated a specificity of 95.3% (95% confidence interval (CI): 92.7-97.0), sensitivity of 86.5% (95% CI: 79.8-91.2), positive predictive value of 87.0% (95% CI: 80.4-91.7) and negative predictive value of 95.1% (95% CI: 92.5-96.8). CRBSI/CLABSI and ICU-BSI incidence rates were 3.23/1,000 catheter days (95% CI: 2.91-3.57) and 2.42/1,000 patient days (95% CI: 2.17-2.70), respectively. Most identified microorganisms for CRBSI/CLABSI were
