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: Identifying the risk factors for perioperative myocardial injury/infarction (PMI) is critical to prevent postoperative adverse cardiovascular events. However, whether reducing the preoperative LDL-C can mitigate the risk of PMI remains unclear. We therefore investigated the effect of the preoperative LDL-C level in patients with stable angina pectoris (SAP) or unstable angina pectoris (UAP) on perioperative myocardial injury/infarction (PMI) after elective percutaneous coronary intervention (PCI). Methods: Patients with SAP or UAP who received PCI from January 2021 to June 2023 at one of the two institutions (Hebei Provincial People's Hospital, Handan Central Hospital) were reviewed. The occurrence of PMI was determined based on the elevation of cardiac troponin I (cTnI) after the operation. The preoperative low density lipoprotein cholesterol (LDL-C) level was divided into three grades: low, <1.4 mmol/L; medium, 1.4-1.8 mmol/L; high, >1.8 mmol/L. The relationship between PMI and preoperative LDL-C was analyzed. Results: Of all 308 included patients, 226 did not have PMI and 82 experienced PMI. Positive correlation was found both between PMI and preoperative LDL-C level (r = 0.322, Conclusion: For SAP and UAP patients, decreasing LDL-C to <1.4 mmol/L before elective PCI can reduce the incidence of PMI after the operation. We strongly recommend the practice of sufficiently reducing LDL-C level below 1.4 for patients with SAP or UAP who receive elective PCI.
