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
IntroductionPeripheral arterial disease (PAD) is highly prevalent among cardiovascular diseases. However, the distribution and volume of endovascular diagnostic and therapeutic procedures among institutions have not been thoroughly investigated. This study aimed to determine the number and types of endovascular procedures performed in patients with PAD, both overall and by county, as well as to compare institutional volumes and procedural trends.MethodsWe analyzed interventions performed between 2017 and 2020, including the type of admission, diagnostic procedure group, procedure type, and institution. Institutions were categorized as high-volume if they performed more than 200 procedures annually.ResultsThere was a total of 13,533 procedures. Percutaneous transluminal angioplasty (PTA) with balloon and single-stent PTA with balloon were the most performed interventions. Routine inpatient procedures were more frequent than those performed in day hospitals and increased through 2019, followed by a decline in 2020. The mean annual number of interventions per institution was 96.73 in university hospitals and university hospital centers, 18.12 in general hospitals, and 52.75 in private hospitals. High-volume centers included University Hospital Merkur, Clinical Hospital Center Rijeka, Dubrava University Hospital, and University Hospital Centre Zagreb. The ratio of single-stent to multiple-stent procedures varied across institutions and over time. In general hospitals, single-stent procedures were performed 2.5 times more frequently than multiple-stent procedures. At Clinical Hospital Center Zagreb, this ratio was 6.4-fold higher compared with other university hospitals.ConclusionThe findings of this cross-sectional study suggest centralization of endovascular PAD interventions in higher-level institutions, with lower procedural volumes in smaller centers. Substantial variability in clinical practice patterns may indicate a lack of integrated care pathways, absence of cost-effectiveness frameworks, and limited use of standardized quality indicators.
