Prognostic implications of increased and final quantitative flow ratios in patients treated with drug-coated balloons physiological evaluation after DCB in de novo lesions.
Trial report in BMC cardiovascular disorders, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundFew studies investigated the implications of post-PCI QFR and post-PCI ΔQFR (absolute increase of QFR) in de novo lesions of small coronary disease after drug-coated balloon (DCB).
objectivesWe sought to investigate the prognostic implications of post-PCI QFR and post-PCI ΔQFR in patients who received DCB only.
methodsPatients were divided according to the optimal cutoff value of the post-PCI QFR and the post-PCI ΔQFR. The primary outcome was major adverse cardiovascular events (MACE), including target vessel revascularization (TVR), cardiac death, and myocardial infarction (MI).
resultsThe optimal cutoff values of QFR and ΔQFR for the MACE rate were 0.86 and 0.57, respectively. There were 175 patients (61.2%) with a high QFR (≥ 0.86) and 113 patients (39.5%) with a high ΔQFR (≥ 0.57) after PCI. The MACE rate was significantly higher in patients with a low QFR compared to a high QFR (5.7% vs. 27.0%, hazard ratio [HR]: 3.632, 95% confidence interval [CI]: 1.872 to 7.044, P < 0.001). The MACE rate was higher in patients with a low ΔQFR increase compared to those with high ΔQFR (4.4% vs. 20.2%, HR: 4.700, 95%CI: 2.430 to 9.089, P = 0.001). In multivariable model, a low post-PCI QFR and a low post-PCI ΔQFR was independent predictor of MACE (adjusted HR: 4.071, 95%CI: 2.037 to 8.135, P = 0.001).
conclusionsAfter DCB in de novo lesions of small coronary disease, both post-PCI QFR and ΔQFR showed similar prognostic implications in MACE.
