Posterior Spinal Artery Infarction With Unilateral Lumbar Spinal Cord Lesion: A Challenge in Early Diagnosis.
Article in Journal of general and family medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
A 71-year-old woman presented with acute muscle weakness and paresthesia in her left lower limb with the preceding back pain and impaired deep sensation. Although initial brain and spinal MRI were normal, follow-up spinal MRI confirmed the left-sided posterior lesion at T10 to T12 vertebral level, leading to the diagnosis of posterior spinal artery (PSA) infarction. PSA infarction with unilateral lumbar spinal cord lesion is rare and can mimic cerebral stroke. Clinicians should check for back pain and deep sensation in cases with symptoms of acute unilateral lower limb on suspicion of PSA infarction, even when initial MRI is normal.
