Safety and efficacy of hairy scalp donors in thick split-thickness skin grafting: Healing and complications at donor sites.
Article in JPRAS open, 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
Background: We aimed to investigate how the thickness of removed skin grafts affects the healing time at the donor site, with a focus on the depth of the donor wound and the normal thickness of the scalp. Methods: We examined the outcomes of the donor sites of thick split-thickness skin grafts using hairy scalp skin in 102 Korean patients. We measured the thickness of the scalp donor skin using preoperative ultrasonography, histometric thickness of normal scalp skin in 61 patients, and histometric thickness of the thickest part of the grafted skin after surgery. Results: The mean normal ultrasound thickness of the scalp donors was 1.711 mm, with a mean histometric normal scalp thickness of 1.926 mm (61 cases), mean dermatome depth set of 0.569 mm (22/1000 inches, 22 mils), and mean histometric harvested skin thickness of 0.677 mm. The relationship between healing time and percentage of histometric graft thickness per ultrasonographic normal scalp skin thickness was statistically significant and correlated positively. Healing of the partial portion of the scalp was delayed in 9 donors due to infection and folliculitis. Scalp donor wounds healed during postoperative days 6 and 15, except for the ones with infected portions. Conclusion: Patients in this study successfully achieved scarless regenerative healing of their scalp donor wounds. Furthermore, adequate wound dressing can prevent alopecia and scarring of infected donor wounds. The results of this study offer valuable insights into the advantages of using scalp skin in grafts, underscoring its potential as a preferred option for achieving optimal regenerative healing.
