Comparative Analysis of Three Different Optimization Procedures for Coronary Bifurcation Provisional Stenting: Insights from Micro-Computed Tomography and Optical Coherence Tomography Imaging of Bench Deployments.
Article in Acta Cardiologica Sinica, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 4 papers.
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: Post-dilation with kissing balloon dilation remains controversial in the 1-stent approach, but many technical improvements are possible to refine the final results. This study aimed to evaluate the results of different side-branch (SB) ostial treatments after main vessel stenting, including ostial optimization technique (OOT), simultaneous kissing balloon dilation (KBD) and single balloon dilation (SBD). Methods: Three different ostial side branch treatments (OOT, n = 6; KBD, n = 6; SBD, n = 6) were emulated in a synthetic bifurcated phantom using a second-generation sirolimus-eluting stent (Firebird2TM, Microport, Shanghai, China). Micro-computed tomography (micro-CT) and optical coherence tomography (OCT) were performed to assess morphologies. Results: Compared to the non-OOT procedures (SBD and KBD), OOT was characterized by the sequential dilation of two snuggling balloons, creating a longer valgus struts length (OOT: 2.13 ± 0.30 mm, SBD: 1.23 ± 0.34 mm, KBD: 1.11 ± 0.39 mm, p < 0.01), broader angulation between the main-branch and valgus struts axes (OOT: 42.72 ± 0.91°, SBD: 25.77 ± 7.81°, KBD: 31.78 ± 1.34°, p < 0.01), shorter neocarina length (OOT: 0.28 ± 0.31 mm, SBD: 0.64 ± 0.38 mm, KBD: 1.11 ± 0.37 mm, p < 0.01), larger SB ostial area (OOT: 6.76 ± 0.17 mm Conclusions: OOT, consisting of an initial proximal optimizing technique (POT) and sequential snuggling balloon dilation and then re-POT, significantly optimized the results of provisional bifurcation treatment. The physiological and clinical significance of our observations await further clarification.
