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
objectivesRecanalization of peripheral chronic total occlusions (CTO) is technically challenging especially in cases of in-stent and/or pre-stent and heavily calcified lesions. A high-frequency vibrational device (HFVD) was first used as a secondary-intention device in CTO recanalizations when they were refractory to a guidewire. The aim of this study was to assess the safety and efficacy of the HFVD as a first-line treatment for challenging CTOs and thus to define the percutaneous intentional intraluminal-assisted recanalization (PILAR) technique.
methodsFifty-two patients were treated with the HFVD. Only challenging CTOs were included: 7 pre-stent, 7 in-stent, and 38 highly calcified CTOs. Technical success was defined as the ability to cross the CTO using the HFVD. Secondary outcome was defined as successful intraluminal crossing. Safety endpoints were procedure-related thromboembolism or perforation. Patients were followed up at 3 months and 1 year.
resultsThe technical success rate for recanalization was 90%, of which 83% were intraluminal. The mean recanalized length was 91 ± 44 mm. One thromboembolic complication occurred, which was subsequently treated with thromboaspiration. Three-month and 1-year primary patency rates were 92% and 79%, respectively.
conclusionsHFVD-based PILAR is a safe and effective technique for in-stent or pre-stent CTO recanalization of long and calcified lesions. KEY POINTS: • Intraluminal recanalization is the preferred procedure in heavily calcified or pre-/in-stent CTO. • First-line use of assisted intraluminal recanalization for CTO defines the PILAR technique. • HFVD-based PILAR is safe and provides a high success rate for challenging CTO recanalization.
