Modified National Early Warning Score 2, warning system for predicting treatment outcomes in patients with emphysematous pyelonephritis.
Article in World journal of nephrology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Emphysematous pyelonephritis (EPN) is a severe, a lethal necrotizing upper urinary tract infection, characterized by gas production within the renal parenchyma, collecting system, or perinephric tissue. EPN is emerging as a significant concern, necessitating early diagnosis, severity assessment, and timely intervention to improve outcomes. This study proposes a modified National Early Warning Score 2 (mNEWS 2) to enhance risk stratification and predictive accuracy in EPN management. The mNEWS 2 refines the original NEWS 2 system, which aggregates 6 physiological indicators (body temperature, systolic blood pressure, pulse rate, oxygen saturation, breathing rate, and degree of consciousness), by incorporating weighted risk stratification indices and specific cutoff values derived from clinical observations, statistical modeling, and predictive performance analysis. A pilot study identified optimal thresholds, with a score of 15 maximizing predictive performance for mortality risk and intervention needs, validated through receiver operating characteristic curve analysis. So, the mNEWS 2 score represents a significant advancement in EPN management, offering improved risk stratification and treatment outcomes.
