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
Flow diverter placement for fetal-type posterior communicating artery (PCom) aneurysms is known to result in a low complete occlusion rate due to the tendency for flow out toward the PCom, resulting in residual blood flow within the aneurysm. Here, we report a case of ischemic complications after flow diverter treatment for a fetal-type PCom bifurcation aneurysm. Seventy-five-year-old woman had unruptured left fetal-type PCom. Pipeline placement with coils was performed. Eight months after surgery, the patient developed transient paralysis of the right and left lower extremities due to scattered embolic ischemic complications in the perfusion area of the fetal PCom after reducing the antiplatelet medication dose. Tight packing was performed within the aneurysm from P1 via the PCom. Transient paralysis of the right upper and lower extremities was observed due to acute infarction in the tuberothalamic artery region after operation. Flow diverter placement for fetal-type PCom aneurysms is difficult to achieve complete occlusion, and when aiming for complete occlusion, it is necessary to consider the risk of ischemic complications in the tuberothalamic artery.
