Consistency and Risk Stratification Performance of 4 Society for Cardiovascular Angiography and Interventions SHOCK Stage Definitions: A Retrospective Study.

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
backgroundCardiogenic shock (CS) is a critical condition associated with high mortality rates, making prompt diagnosis essential for timely interventions that may improve patient outcomes. The Society for Cardiovascular Angiography and Interventions (SCAI) SHOCK Stage Classification is a validated tool for assessing CS and predicting patient outcomes. Here, we evaluated how different parameter definitions affect SCAI stage adjudication, hypothesizing that variations may influence stage determination and the overall assessment of CS.
methodsAll patients diagnosed with CS or conditions leading to CS at the University Medical Center Mannheim, Germany, from January 2018 to June 2022 were included in the study. SCAI SHOCK stages were assigned retrospectively on the basis of 4 previously published studies. The distribution of SCAI SHOCK stages, outcomes, classification concordance, and predictive performance were assessed.
resultsFrom January 2018 to June 2022, we identified 1303 patients on the basis of
conclusionsOur study demonstrates a moderate to strong concordance and comparable prognostic performance across different SCAI SHOCK Stage Classification frameworks in evaluating patients with CS. Despite differences in stage assignments, all frameworks effectively stratified patients by clinical severity. Comparable stage assignment in retrospective studies requires further standardization of the SCAI SHOCK Stage Classification system.
