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: The Society of Cardiovascular Angiography and Intervention (SCAI) has defined 5 stages of cardiogenic shock (CS). In patients with acute myocardial infarction (AMI) who initially present in stable hemodynamic condition (SCAI CS stage: A or B), CS stages could deteriorate despite therapeutic management. However, deterioration of SCAI CS stages after AMI remains to be fully characterized. Therefore, the current study sought to investigate the frequency and clinical characteristics about deterioration of SCAI CS stages after AMI. Methods: We retrospectively analyzed 347 patients in a derivation cohort and 163 patients in a validation cohort who had AMI (SCAI shock stage upon arrival: A/B) and underwent percutaneous coronary intervention (PCI) at National Cerebral and Cardiovascular Center, Suita, Japan (enrolment period of study subjects: 2019.07.01-2022.09.30). Deterioration of CS (D-CS) was defined as SCAI shock stage C-E after PCI. Clinical characteristics and in-hospital mortality were compared according to D-CS status. Adjusted hazard ratios (HRs) for in-hospital mortality were calculated with multivariate Cox proportional hazards models that included variables with P<0.10 in univariate models. Uni- and multivariate logistic regression analyses were used to identify predictors of D-CS. Results: D-CS occurred in 17.3% (60/347) of the derivation cohort. Patients with D-CS had lower systolic blood pressure (BP) (P<0.001) and left ventricular ejection fraction (LVEF) (P<0.001) upon arrival with a higher proportion of initial Thrombolysis in Myocardial Infarction (TIMI) grade flow 0 or 1 (P=0.002). During hospitalization (13.9±9.4 days), D-CS was associated with higher in-hospital mortality [adjusted HR, 12.95; 95% confidence interval (CI): 1.46-114.97; P=0.02]. Initial systolic BP, LVEF, and TIMI grade flow 0 or 1 independently predicted D-CS. The D-CS risk score including these variables satisfactorily predicted D-CS [area under the curve (AUC), 0.749; 95% CI: 0.651-0.848] and in-hospital mortality (AUC, 0.961; 95% CI: 0.914-1.000) in the validation cohort. Conclusions: D-CS occurred in 17.3% of patients with AMI initially presenting in stable condition and increased the risk of in-hospital mortality. Our D-CS risk score (initial systolic BP, LVEF, and TIMI grade flow) could be helpful to predict D-CS.
