Sex-specific differences in the anatomical localization and severity of coronary artery disease: differential impact of conventional cardiovascular risk factors.

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
backgroundSex differences in coronary artery disease (CAD) are well recognized. Whether conventional cardiovascular risk factors (CVRFs) exert differential effects on anatomical localization and stenosis severity on coronary arteries (CA) remains uncertain. We aimed to evaluate sex-specific associations between major CVRFs and CA involvement.
methodsWe analyzed 978 patients undergoing coronary angiography (CAG) between 2017-2023. Sex, age, hypertension (HT), diabetes mellitus (DM), history of CAD (HCAD), smoking, Syntax scores (SS), lipid parameters and creatinine levels were assessed. Segment-based coronary involvement was evaluated using correlation and multivariable regression analyses.
resultsWomen were older (p < 0.001), had higher rates of HT (p = 0.001), DM (p = 0.026) and higher total cholesterol (p = 0.001), LDL-C (p = 0.001) and HDL-C levels (p = 0.001). In contrast HCAD (p = 0.001), smoking (p = 0.009) and SS (p < 0,01) were higher in men. HT was associated with circumflex (Cx) (p = 0.029) and right coronary artery (RCA) (p = 0.002) involvement in women; with proximal left anterior descending artery (LAD) (p = 0.024) involvement in men. DM showed significant associations with LAD (p = 0.001), 1st diagonal (Dg) (p = 0.003), Cx: (p = 0.001) and RCA (p = 0.001) territories in women. HCAD was associated with proximal LAD (p = 0.013), CX (p = 0.006) and RCA (p = 0.016) in men; proximal LAD (p = 0.047), CX (p = 0.014) and RCA (p = 0.009) in women. Lipid parameters had no association with CA involvement in either sex after adjustment. Creatinine levels were associated with RCA and CX involvement in women and with LMCA and proximal LAD territories in men.
conclusionCVRFs exert sex-specific effects on CA, highlighting the importance of sex aware risk stratification in CAD.
