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
backgroundThe Multidimensional Prognostic Index (MPI) derived from Comprehensive Geriatric Assessment (CGA) is a validated tool for predicting mortality and hospital outcomes, but it requires trained staff and time-consuming evaluation. The Blaylock Risk Assessment Screening Score (BRASS) is a simpler, nurse-administered tool primarily designed for discharge planning. Whether BRASS provides comparable short-term prognostic value to MPI remains uncertain.
objectivesTo compare the ability of MPI and BRASS to predict in-hospital mortality, length of stay (LOS), and non-home discharge among hospitalized older adults.
methodsWe analyzed data from 893 patients aged ≥ 65 years admitted to the acute geriatric unit of S. Giovanni-Addolorata Hospital (Rome, Italy) as part of the GRACE study (2022–2024). MPI and BRASS scores were collected within 48 h and 24 h of admission, respectively. Associations of each tool with in-hospital mortality, non-home discharge, and LOS were assessed using multivariable logistic and linear regression models. The predictive performance of the two tools was subsequently compared through receiver operating characteristic (ROC) curve analysis.
resultsHigher MPI and BRASS risk categories were associated with increased mortality, longer LOS, and higher rates of non-home discharge (p < 0.0001 for all). In multivariable analysis, each 0.25-point increase in MPI score was independently associated with higher odds of in-hospital mortality (aOR 3.57; 95% CI 2.10–6.08; p < 0.0001) and non-home discharge (aOR 3.58; 95% CI 2.10–6.08; p < 0.0001). Similarly, each 4-point increase in BRASS score predicted higher mortality (aOR 1.46; 95% CI 1.22–1.75; p < 0.0001) and non-home discharge (aOR 1.37; 95% CI 1.23–1.52; p < 0.0001). In ROC analysis, both tools showed similar performance for mortality (AUC 0.766 vs 0.739; p = 0.26), and non-home discharge (AUC 0.704 vs 0.698; p = 0.75).
conclusionsMPI and BRASS were associated with a higher risk of in-hospital mortality, non-home discharge and prolonged length of stay. The tools showed comparable predictive ability for both mortality and non-home discharge. Given its simplicity and minimal resource requirements, BRASS may represent a rapid and cost-effective screening tool to complement—or, when appropriate, precede—a full CGA-based MPI assessment.
