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
Lateral medullary infarction is rarely associated with Opalski syndrome and autonomic dysfunction. Herein, we present the first case involving a 66-year-old patient with cancer who developed mild dysarthria, left-sided Horner's syndrome and lower limb-dominant ataxic hemiparesis, reduction in right-sided painful thermal sensation, and severe truncal ataxia, followed by orthostatic headache. The Schellong test revealed severe orthostatic hypotension. The patient was diagnosed with Opalski syndrome associated with headache attributed to orthostatic hypotension caused by the cerebral infarction in the caudal part of the lateral medulla oblongata. The patient's headache had poor response to analgesics. However, it resolved with orthostatic hypotension improvement.
