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: A drug-coated balloon (DCB) allows treating the coronary artery lesions without permanent implantation of a metallic stent. International guidelines recommend DCB for the treatment of in-stent restenosis (ISR). Although DCB showed promising results in treating ISR, their role is still not well established in the broader clinical practice. Objective: In this short report, we describe our institution's four-year initial experience in using DCB angioplasty, and compare the characteristics and outcomes of the patients treated with DCB with those treated with drug-eluting stent (DES) for ISR. Methods: This is a single-center retrospective study of patients who underwent coronary angioplasty with either DCB or DES from January 1, 2018 to November 30, 2021 at the Heart Hospital in the State of Qatar. Results: A total of 572 patients with ISR were recruited, 132 and 440 patients were in the DCB and DES group, respectively. In the DCB group, the median age was 57.9 years and there were 117 (88.6%). There was no significant difference between the DCB and DES groups in term demographics, comorbidities, coronary angiography indication or characteristics, and clinical outcomes. With regards the clinical outcomes, 13 patients (9.8%) underwent angioplasty for ACS and chest pain in the DCB group. The median time to the first event was a median of 480 days (16 months). Conclusion: The use of DCB is increasing in Qatar. The initial experience was limited to its use in ISR. Patient characteristics, angiographic characteristics, and clinical outcomes in the DCB group did not significantly differ from those in the DES group. More studies are needed to evaluate the use of DCB in wider indications.
