Potential predictors of side-branch occlusion in bifurcation lesions after percutaneous coronary intervention: a coronary CT angiography study.

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
purposeTo identify potential predictors of side-branch occlusion after main-vessel (artery) stent implantation in bifurcation lesions by using coronary computed tomography (CT) angiography. MATERIALS AND
methodsThis retrospective study was approved by the institutional review board; informed consent was waived. Sixty-five patients with de novo bifurcation lesions underwent coronary CT angiography before percutaneous coronary intervention. By defining side-branch occlusion as Thrombolysis in Myocardial Infarction flow grade 2 or lower, coronary CT angiography plaque characteristics associated with side-branch occlusion (ie, plaque morphology and composition) were analyzed. A multiple logistic regression analysis was undertaken to determine independent potential predictors of side-branch occlusion.
resultsOf 65 patients enrolled, 12 patients (18%) had side-branch occlusion after main-vessel stent implantation. Patients with side-branch occlusion had larger mean plaque thickness in the side-branch side of the proximal main vessel (2.29 mm ± 1.87 [standard deviation] vs 1.29 mm ± 1.43, P = .043), larger plaque thickness in the noncarinal side of the side branch (1.43 mm ± 1.18 vs 0.51 mm ± 0.65, P < .001), smaller side-branch lumen diameter (1.24 mm ± 0.74 vs 1.87 mm ± 0.71, P = .007), and higher diameter stenosis (50.9% ± 24.0 vs 25.5% ± 25.3, P = .002) compared with those without side-branch occlusion. The cutoff value of proximal main vessel plaque thickness was 2.7 mm (area under the curve [AUC], 0.67; 95% confidence interval [CI]: 0.48, 0.86) and of side-branch-diameter stenosis was 40% (AUC, 0.79; 95% CI: 0.67, 0.92). Lesions with plaque thickness in proximal main vessel greater than 2.7 mm and side-branch-diameter stenosis greater than 40% were associated with a 5.6-fold and 6.2-fold, respectively, increased risk of side-branch occlusion.
conclusionPotential coronary CT angiography predictors of side-branch occlusion in bifurcation lesions are plaque thickness in the side-branch side of the proximal main vessel, plaque thickness in the noncarinal side of the side branch, side-branch lumen diameter, and side-branch-diameter stenosis. These potential predictors might guide operators planning the optimal strategy for treating bifurcation lesions.
