Dose-Dependent Effects of Minocycline on Facial Nerve Regeneration: A Microscopic and Molecular Study.
Article in Aesthetic plastic surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
Injuries to the facial nerve present clinical difficulties with frequently unfavorable results. This study uses histological, electrophysiological, and LC-MS/MS-based metabolomic techniques to examine the dose-dependent effects of locally administered minocycline on facial nerve regeneration. For that purpose, the rats were divided into three groups. Following nerve transection and suturing, the rats from Group A received sterile water, those from Group B received 40 μg of minocycline, and those from Group C received 100 μg of minocycline locally on the suture line in 20 μL fibrin gel. Nerve regeneration was evaluated using LC-MS/MS metabolomics and histopathological analyses at the end of the 28th day. Electrophysiological analyses were performed on the 0th day and postoperative 1, 2, and 4 weeks. In the sections of Group A, edema within the myelin sheath and beneath the perineurium were the most conspicuous findings. Vacuolar characteristics within the myelin sheath were also detectable. Groups B and C exhibited preserved architecture with minimal edema. Nerve fiber density was similar across groups (p > 0.05). Metabolomics analyses revealed reduced betaine and elevated proline levels in Group C vs. Group A (p < 0.05). Compound muscle action potential values improved over time, especially in Group B (p = 0.013), peaking at week 2. Both doses of minocycline have been found beneficial on facial nerve regeneration. Although Group C showed superior histological and biochemical outcomes, Group B induced greater clinical and electrophysiological outcomes. We suggest that minocycline is effective on nerve regeneration in a dose-dependent manner.No Level Assigned This journal requires that authors assign a level of evidence to each submission to which Evidence-Based Medicine rankings are applicable.
