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
backgroundThe clinical impact of different types of angiographic complications during elective PCIs remains largely unexplored.
aimsTo explore the incidence, management, and outcomes of angiographic complications by type and severity during non-urgent, non-CTO PCIs.
methodsClinical and procedural characteristics were prospectively collected and entered in a catheterization laboratory database, including a section dedicated to PCI complications, from 2015 to 2024. Angiographic complications were classified in eight categories: dissections, perforations, device entrapment/fracture, side branch flow impairment, vessel thrombosis, distal embolization, and any temporary or persistent slow-flow or total occlusion. 30-days and 1-year all-cause mortality were compared between two cohorts with or without angiographic complications, after a propensity score matching for demographic, clinical, procedural and anatomical characteristics.
resultsOut of 8401 non-urgent PCIs, 420 (5.0%) presented ≥ 1 angiographic complication (417 patients), with the following incidences: 2.2% iatrogenic dissections, 1.2% side branch flow impairment, 1.2% slow flow, 1.0% vessel occlusion, 0.4% distal embolization, 0.4% vessel thrombosis, 0.4% perforations, 0.1% device entrapment/fracture. Patients with angiographic complications showed a significantly higher risk of 30-days mortality compared to the propensity score-matched cohort without angiographic complications (4.1% vs. 1.6%, p = 0.045). Age, a previous hospitalization for decompensated heart failure, and a procedure on severely calcified lesions were independently associated with 1-year mortality in patients with angiographic complications.
conclusionAngiographic complications during elective PCI significantly increase 30-day mortality compared with uncomplicated PCI. A history of decompensated heart failure warrants particular caution in the event of angiographic complications, as it is associated with an increased risk of mortality within the first year after the procedure.
