Trial report in BMC veterinary research, 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
backgroundPostmastectomy complications remain relevant in veterinary surgery. Although cold atmospheric plasma (CAP) and photobiomodulation (PBM) may improve tissue repair, evidence on their combined use is limited. This exploratory pilot study evaluated CAP-PBM therapy in nine female dogs undergoing unilateral mastectomy.
methodsA prospective, randomized, blinded, intra-individual controlled clinical study was conducted in nine female dogs with mammary neoplasia undergoing clinically indicated unilateral mastectomy. In each dog, one half of the surgical wound was randomly assigned to receive sequential CAP and PBM therapy, while the contralateral half remained untreated and served as an intra-individual control. Evaluations were performed on postoperative days 3, 7, and 14 (D3, D7, and D14) using macroscopic scoring systems, ultrasonography, and infrared thermography; histomorphometric analysis was performed only on D7.
resultsTreated regions showed significantly lower Modified Hollander Scar Scale (p < 0.001) and Modified Draize Scoring System (p = 0.001) scores. Ultrasonographic assessment demonstrated lower semiquantitative scores (p = 0.029) and reduced subcutaneous thickness (p = 0.034), especially during the early postoperative period. Thermographic findings did not differ significantly between groups. Histological analysis revealed numerically greater re-epithelialization in treated areas, although without statistical significance (p > 0.05).
conclusionsIn this exploratory pilot study, combined CAP + PBM therapy was associated with improved early macroscopic and ultrasonographic healing parameters after mastectomy in female dogs. These preliminary findings support further investigation of CAP + PBM as a promising non-invasive adjuvant strategy for postoperative wound management, pending confirmation in larger, adequately powered randomized studies.
