Minimizing Contrast Use in High-Risk Patients: A Case Report of Optical Coherence Tomography-Guided Percutaneous Coronary Intervention.
Article in Cureus, 2026. 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
Contrast-induced nephropathy (CIN) is a concerning complication following percutaneous coronary intervention (PCI), particularly in patients with preexisting renal impairment, diabetes, hypertension, and heart failure. Intravascular imaging with optical coherence tomography (OCT) requires contrast flushes for clearing blood and can cause CIN. We present a patient at high risk for developing CIN who underwent PCI with minimal contrast use, aided by OCT with saline flushes and a parallel wire technique to visualize plaque morphology and guide stent placement, while avoiding excessive contrast exposure. The patient had no worsening of kidney function after the procedure. Despite the absence of intravascular ultrasound, the parallel wire technique facilitated accurate stent positioning, contributing to a successful PCI outcome. This case underscores the importance of minimizing contrast use in high-risk patients and highlights the efficacy of OCT with saline flushes as an alternative imaging modality in reducing the risk of CIN during PCI.
