Impact of intracoronary reteplase during primary percutaneous coronary intervention on infarct size in large anterior myocardial infarction: rationale and design of the RECOVER II trial.
Article in Cardiovascular diagnosis and therapy, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04571580 (Effect of Low-dose Intracoronary Reteplase During Primary Percutaneous Coronary Intervention on Myocardial Infarct Size in Patients With Acute Myocardial Infarction), which is not on this map. Not yet cited in PubMed.
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.

Abstract
Background: Thrombus embolization and microvascular obstruction during percutaneous coronary intervention (PCI) in ST-segment elevation myocardial infarction (STEMI) is commonly detected, which causes inadequate myocardial perfusion and elevated infarct size. An approach with low-dose intracoronary fibrinolytic treatment for reducing distal embolization and improving myocardial reperfusion in high-risk STEMI cases remains controversial. Methods: The RECOVER II study represents a multicenter, randomized, double-blind, parallel-group trial assessing low-dose adjunctive intracoronary reteplase during primary PCI in individuals with large anterior myocardial infarction and thrombus determined by angiography. The trial will enroll 306 cases who present within 12 h following STEMI for proximal or mid left anterior descending artery occlusion undergoing primary PCI. Cases will be randomized to receive a bolus intracoronary reteplase at 9 mg or 18 mg Results: The primary outcome will be infarct size assessed by late gadolinium-enhanced magnetic resonance imaging (MRI) (% of left ventricular mass) on day 7 after enrollment. Secondary outcomes will include the amount of microvascular obstruction and myocardial salvage index examined via MRI on day 7, angiographic measures of reperfusion [Thrombolysis in Myocardial Infarction (TIMI) coronary flow grade, TIMI frames count and myocardial blush grade], incidence of complete ST-segment resolution at 2 hours after reperfusion, area under the curve for troponin T, and rates of major adverse cardiovascular events at 30 days. Conclusions: RECOVER II will determine whether the addition of low-dose intracoronary reteplase early after wire-crossing as an adjunct to reperfusion treatment reduces infarct size in individuals with large anterior myocardial infarction.
