Scurvy: a rare cause of haemarthrosis.
Article in BMJ case reports, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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 male in his 60s with a history of previously treated locally advanced head and neck cancer presented to the emergency department with atraumatic left knee pain and upper and lower extremity ecchymoses that had been present for 3 weeks. His initial laboratory results showed a normocytic anaemia, normal platelet count, slightly abnormal coagulation studies and normal inflammatory markers. Arthrocentesis of the left knee revealed haemarthrosis, and additional laboratory workup found an undetectable serum vitamin C (ascorbic acid) level consistent with scurvy. It was determined that scurvy had predisposed the patient to injury, leading to haemarthrosis. Following vitamin C supplementation, dietary and activity modifications, and acetaminophen as needed, the patient's serum vitamin C level normalised and his left knee pain and swelling improved. Scurvy is a rare cause of haemarthrosis, but it should be recognised in at-risk patients since treatment is effective.
