Acute-onset Copper Deficiency Following Surgery in a Dialysis Patient: Diagnostic Challenges and Risk Factor Interaction.
Article in Internal medicine (Tokyo, Japan), 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
Copper deficiency is a rare but critical cause of anemia and neurological impairment. We herein report a hemodialysis patient who developed acute-onset copper deficiency after spinal surgery with zinc supplementation, despite no gastrointestinal surgery. The anemia was unresponsive to oral copper but improved with intravenous administration. We analyzed clinical data from copper-deficient patients at our institution and in the literature and compared them with matched dialysis controls. Our findings indicate the cumulative impact of multiple risk factors. Clinicians should consider functional copper deficiency in dialysis patients with unexplained anemia after surgery.
