Clinical Significance of Hyperhomocysteinemia in Free Flap Failure: A Case Report.
Article in Archives of plastic surgery, 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
Failure of a microvascular free flap remains rare, yet multiple failures can occur, particularly in the presence of hypercoagulable conditions. This case series highlights our experience with a rare hypercoagulable state: hyperhomocysteinemia. We present two cases of patients with hyperhomocysteinemia in this report. High-dose heparinization was administered to both patients, resulting in successful salvage of one flap and failure of the other. Notably, one patient had a history of prior free flap failures. However, after correcting hyperhomocysteinemia, subsequent free flaps were successful. In cases of detected complications, a coagulability study is warranted, and adjustments to anticoagulation treatment may be necessary. Furthermore, when a history of flap failures is evident, screening for hyperhomocysteinemia may be warranted, with correction made prior to reconstruction.
