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
purposeWe aimed to demonstrate the safety and feasibility of revascularization of chronic total occlusion of the superficial femoral artery (SFA) using the transpedal approach and describe a new technique called "re-route".
methodsThe study included all consecutive patients who had chronic total occlusions at the level of SFA and underwent retrograde treatment through a pedal artery intervention between September 2017 and October 2019. Balloon angioplasty was applied as the first treatment option. After angioplasty, bailout stenting was performed when necessary in patients with indications. If the common femoral artery lumen could not be reached from the SFA ostium, the re-route technique was used. Technical success was defined as revascularization with residual stenosis of less than 30%.
resultsTwenty-five SFAs were revascularized in 23 patients (17 males; mean age, 66±7.3 years) by angioplasty in 5 SFAs and angioplasty and stents in 20 SFAs. While the transpedal approach was applied after the failure of antegrade recanalization in three patients, it was used as the first treatment route in the remaining cases. The re-route technique was applied in 7 patients, with a 100% technical success rate. The mean follow-up was 15.3 months (range, 12-18 months). The primary patency rate was 78% at one year.
conclusionThe retrograde transpedal approach is a safe and successful technique for chronic total occlusion recanalization and carries a low risk of complications. In order to increase technical success, the re-route technique can be used as an alternative re-entry method.
