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

backgroundIn response to the COVID-19 pandemic, Ontario issued a declaration of emergency, implementing public health interventions on March 16, 2020.

methodsWe compared cardiac catheterization procedures for ST-elevation myocardial infarction (STEMI) between January 1 and May 10, 2020 to the same time frame in 2019.

resultsFrom March 16 to May 10, 2020, after implementation of provincial directives, STEMI cases significantly decreased by up to 25%. The proportion of patients who achieved guideline targets for first medical contact balloon for primary percutaneous coronary intervention (PCI) decreased substantially to 28% (median, 101 minutes) for patients who presented directly to a PCI site and to 37% (median, 149 minutes) for patients transferred from a non-PCI site, compared with 2019.

conclusionsSTEMI cases across Ontario have been substantially affected during the COVID-19 pandemic.
