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

Background: Periprocedural myocardial injury (PMI) is a common complication of percutaneous coronary intervention (PCI). Elevated post-PCI index of microcirculatory resistance (IMR) has been linked to PMI. The angiography-derived IMR (angio-IMR) serves as a pressure-wire-free method to assess coronary microvascular function. This study aimed to establish the association between post-PCI angio-IMR and PMI. Methods and Results: We retrospectively analyzed 101 consecutive elective PCI cases where PMI diagnosis and post-PCI angio-IMR calculation were feasible. Angio-IMR was computed using computational flow and pressure simulations. Patients were categorized into 2 groups based on PMI status: PMI (n=33), and non-PMI (n=68). The PMI group had significantly higher post-PCI angio-IMR values than the non-PMI group (31.8±5.9 vs. 23.8±6.0; P<0.001). Both univariate and multivariate logistic regression analyses revealed an association between post-PCI angio-IMR and PMI. Patients with post-PCI angio-IMR ≥29 had a significantly higher incidence of PMI (67.6% vs. 12.5%; P<0.001). Conclusions: Increased post-PCI angio-IMR values were strongly associated with PMI. Post-PCI angio-IMR might serve as a useful non-invasive predictive of PMI following elective PCI.
