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
introductionAneurysms of peripheral foot arteries are extremely rare. Dorsalis pedis artery aneurysms account for 0.5% of peripheral artery aneurysms of the lower limbs. Here, we present a case of pseudoaneurysm of the first dorsal metatarsal artery of the foot and discuss the therapeutic strategy based on a literature review. CASE PRESENTATION: A 76-year-old man with no history of foot trauma presented with pain and a pounding mass in the dorsum of the left foot. Echography revealed a 29 × 18 × 20 mm saccular aneurysm with to-and-fro blood flow. Contrast-enhanced computed tomography revealed an aneurysm in the first dorsal metatarsal artery. Angiography of the aneurysm revealed no arterial drainage. Embolization was subsequently performed only for the feeding artery, which was the proximal first dorsal metatarsal artery, using the 2 Target nanocoils (Stryker; Boston, MA, USA), resulting in successful occlusion. However, echography performed a few months after embolization revealed a recurrence of blood flow and enlargement of the coiled aneurysm. Nine months after embolization, the pain in the dorsum of the foot recurred. Therefore, we performed a surgical resection of the dorsal metatarsal artery aneurysm (38 × 26 × 26 mm) under general anesthesia. The first distal dorsal metatarsal artery exhibited pulsatile bleeding, and angiography of the distal dorsal metatarsal artery revealed a patent pedal arch and posterior tibial artery. Therefore, revascularization was not performed. The postoperative course was uneventful. The pathological examination indicated that the mass was a pseudoaneurysm.
conclusionsThe treatments for peripheral foot artery aneurysms include observation, thrombin injection, ultrasound compression, embolization, surgical excision, and ligation. As the long-term outcomes of embolization for such aneurysms are unknown and cases are limited, surgical excision that is safe and definitive is recommended as the first-line treatment.
