1 · What the graph read from it

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.

2 · The registry

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

backgroundThere are limited data on the prevalence and outcomes of chronic total occlusions (CTO) of the coronary artery in acute myocardial infarction with cardiogenic shock (AMI-CS) patients.

methodsUsing the National Inpatient Sample, all admissions with AMI-CS that underwent diagnostic angiography between January 1, 2008, and December 31, 2014, were included. CTO, percutaneous coronary intervention (PCI), comorbidities and concomitant cardiac arrest was identified for all admissions. Outcomes of interest included temporal trends, in-hospital mortality, and resource utilization in cohorts with and without CTO.

resultsIn this 7-year period, 163,628 admissions with AMI-CS admissions met the inclusion criteria, with 68% being ST-elevation AMI-CS. CTO was noted in 27,343 (16.7%) admissions, with an increase in prevalence during the study period. The cohort with CTOs was more likely to be male and bearing private insurance. The CTO cohort had higher cardiovascular comorbidity, higher rates of cardiac arrest and higher use of PCI and mechanical circulatory support. The presence of a CTO was independently associated with higher in-hospital mortality (adjusted odds ratio 1.20 [95% confidence interval 1.16-1.23];

conclusionsIn this cohort of AMI-CS admissions that underwent diagnostic angiography, the presence of a CTO identified a higher risk cohort that had higher in-hospital mortality.
