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 AND
aimThis prospective study investigated plaque morphologies based on the underlying culprit lesion pathology in relation to the Atherogenic Index of Plasma (AIP) in patients with acute ST-elevated myocardial infarction (STEMI) who underwent primary percutaneous coronary intervention and optical coherence tomography (OCT) for assessment of culprit lesions. The aim of the study was to elucidate the effects of the AIP index and plaque type on the incidence of major adverse cardiovascular events (MACEs).
methodsA total of 274 patients with STEMI aged ≥ 18 years who underwent pre-intervention OCT imaging of culprit lesions between March 2017 and March 2019 were enrolled. AIP index was calculated using the formula: log 10 (triglycerides [TG]/ high-density lipoprotein cholesterol [HDL-C]). We stratified the cohort into four groups according to the presence of Thin-Cap Fibroatheroma (TCFA), as assessed by OCT, and the cutoff value of AIP: Group I consisted of patients with AIP < cutoff & without TCFA; Group II had AIP < cutoff & with TCFA; Group III included those with AIP > cutoff & without TCFA; and Group IV comprised patients with AIP > cutoff & with TCFA. OUTCOMES: Patients in Group IV exhibited a higher prevalence of Diabetes Mellitus (p = 0.012), elevated triglyceride-glucose index (TyG) levels (p < 0.001), increased LDL-C levels (p = 0.002), higher triglycerides levels (p < 0.001), and elevated total cholesterol (p = 0.001), indicating accelerated atherosclerosis. Furthermore, individuals within higher tertiles of AIP demonstrated a greater frequency of healing plaques (p = 0.021). Among patients with diabetes mellitus (DM), the AIP index exhibited a correlation with the healing of plaques (p < 0.05). Multivariable Cox regression analysis revealed that the incidence of MACEs among patients in Group IV (AIP > cutoff & with TCFA) increased by compared to those in Group I. Kaplan-Meier analyses confirmed risk stratification for MACEs based on interactions between AIP-TCFA interaction (log-rank p = 0.027), AIP-plaque interaction (log-rank p = 0.033), AIP-mixed plaque interaction (log-rank p = 0.041), AIP-lipid plaque interaction (log-rank p < 0.001), AIP- macrophage interaction (log-rank p = 0.032).
conclusionMicrostructural features observed via OCT for culprit lesions, combined with the AIP index-an important marker for cardiovascular disease-may be utilized clinically to support risk stratification and predict adverse events among STEMI patients.
