Efficacy and Safety of Hyaluronic Acid Injection for Labia Majora Atrophy in the Chinese Population.
Article in Aesthetic plastic surgery, 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
backgroundLabia majora atrophy can lead to loss of vulvar protection, increased mucosal exposure, pruritus, and psychosocial distress. Hyaluronic acid (HA) injection is an effective, minimally invasive option for vulvar rejuvenation; however, evidence specific to Chinese women remains limited.
objectiveTo evaluate the efficacy, safety, and patient satisfaction of HA injection for labia majora atrophy in Chinese women.
methodsTwenty-three women with moderate to severe labia majora atrophy received HA injection therapy. Efficacy and satisfaction outcomes were assessed at 1, 3, 6, 9, and 12 months using the Labia Majora Atrophy Scale (LMAS), Global Aesthetic Improvement Scale (GAIS), satisfaction scales for labia majora appearance, sexual satisfaction, psychological satisfaction and vulvar pruritus severity. Injection-site reactions were recorded for 4 weeks to evaluate the safety of HA treatment.
resultsAll patients demonstrated significant improvement in LMAS during the first 3 months, with effects maintained for up to 9 months. GAIS scores indicated sustained aesthetic enhancement through 12 months. Sexual and psychological satisfaction and vulvar pruritus all improved significantly between 1 and 9 months. Local injection-site reactions occurring within 4 weeks after injection were mild and transient, including pain in 4 patients (17.4%), swelling in 3 patients (13.0%), tenderness in 2 patients (8.7%), and hard lumps in 2 patients (8.7%). No vascular events, infections, granulomas, or delayed inflammatory reactions occurred.
conclusionsHA injection appears to be a safe and effective treatment option for labia majora atrophy in Chinese women. Treatment was associated with improvements in labia majora appearance, patient-reported sexual and psychological satisfaction, and vulvar pruritus.
