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
purposeOphthalmic artery (OphA) embryogenesis is a complex process with various origins. We describe herein a case in which the OphA stemmed from the persistent primitive trigeminal artery (PPTA), which has never been reported.
methodsA man in his 70s was admitted to our hospital following the sudden onset of altered consciousness. A computed tomography (CT) scan revealed a cerebellar hemorrhage, brainstem compression, and hydrocephalus. The patient underwent emergency craniotomy for hematoma evacuation and decompression. Digital subtraction angiography (DSA) was performed 14 days postoperatively to determine the source of the bleeding.
resultsDSA of the right vertebral artery revealed retrograde filling of the left PPTA, originating from the distal two-thirds of the basilar artery (BA) and extending to the cavernous segment of the left internal carotid artery (ICA) as well as a small artery extending from the intermediate part of the PPTA into the orbit and passing through the superior orbital fissure (SOF). DSA of the left common carotid artery showed the typical supracavernous origin of the OphA.
conclusionThis is the first reported case of double OphAs originating from the ICA and PPTA. It is possible that the OphA traversing the SOF had an anastomosis with the primitive trigeminal artery (PTA) during the embryonic period. Persistence of only the BA side of the PTA results in the OphA originating from the BA, whereas persistence of only the ICA side results in the OphA originating from the meningohypophyseal trunk.
