Correlation Between Intravascular Ultrasound Minimum Luminal Area and Quantitative Minimum Luminal Area in Intermediate Coronary Lesions.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the 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.
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
backgroundChronic coronary syndrome (CCS) is a common disease worldwide. Advances in technology, including quantitative coronary angiography, have improved CCS management. In the present study, we aim to investigate the correlation and agreement between intravascular ultrasound minimum luminal area (IVUSMLA) and quantitative minimum luminal area (QMLA) in CCS patients with intermediate coronary lesions.
methodsData from CCS patients with at least one-vessel coronary occlusion from March 2022 to March 2023 were collected. Gathered data included patients' age, gender, QMLA, IVUSMLA, and patients' previous medical history, including hypertension, diabetes, and smoking. The target lesion in this study was intermediate (50% to 70%) stenosis. Agreement between IVUSMLA and QMLA was assessed using the Bland-Altman plot. A p-value (p) of less than 0.05 was considered statistically significant. R version 4.4.1 software (R Foundation for Statistical Computing, Vienna, Austria) was used for data analysis.
resultsThis study included 52 (59.1%) men and 36 (40.9%) women with a mean age of 67.15 ± 10.63 and 64 ± 12.61 (p = 0.533), respectively. The mean for IVUSMLA and QMLA was 2.80 ± 1.54 and 2.6 ± 1.57, respectively. QMLA was highly correlated with IVUSMLA (r = 0.997; p <0.001). Both QMLA and IVUSMLA had moderately good agreement, presenting with small mean difference values but large values of root mean squared deviation (IVUSMLA - QMLA = 0.13 ± 0.11).
conclusionIVUSMLA and QMLA are highly correlated to each other and have good agreement. So, QMLA can be used instead of IVUSMLA in intermediate coronary lesions.
