When Numbers Lie: A Case Report of Falsely Low Hemoglobin Due to Preanalytical Error Leading to Unnecessary Interventions.
Article in Cureus, 2025. 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
False laboratory values can trigger extensive and unnecessary diagnostic and therapeutic workups. We report a case of falsely diagnosed severe anemia that led to blood transfusions and a comprehensive evaluation, which included aggressive intervention as an endoscopy, before being traced back to a preanalytical sample collection error. Proper phlebotomy technique and education, clinical correlation, and sometimes confirmatory labs can help avoid scenarios like the one presented in this case report.
