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
introductionA retrospective analysis was performed to determine if a glueless, sutureless surgical technique utilizing a triple-layer dehydrated, decellularized amniotic basement membrane tissue, combined with short exposure to mitomycin‑C (MMC), can reduce recurrence and complications after pterygium surgery. Surgical excision remains the mainstay of treatment when symptoms such as vision impairment, foreign body sensation, or cosmetic concerns arise. Wide variation in recurrence rates reflects differences in patient populations, follow-up duration, surgical technique nuances, and definition of recurrence. A dehydrated triple-layer decellularized amniotic basement membrane tissue has unique attributes compared to other amniotic membrane tissue (AMT). Decellularization removes the pro-inflammatory chorion and residual donor cellular debris, thereby reducing immunogenicity while preserving extracellular matrix proteins such as collagen, fibronectin, and laminin, which produce anti-inflammatory cytokines and growth factors, promoting epithelial adhesion and migration. In pterygium excision, decellularized basement membrane may contribute to faster, more comfortable recovery, improved cosmesis, and a reduced risk of recurrence.
methodsA total of 34 eyes from 33 patients underwent pterygium excision using dehydrated, three-layer decellularized basement membrane.
resultsAll patients reported minimal postoperative discomfort, and the operative eyes were relatively quiet with minimal subconjunctival injection. Recurrence was 0% (0/34 eyes) at a mean follow-up of 394 days (range, 174-668). In addition, no pyogenic granuloma, infections, dellen, or melts occurred.
conclusionsCompared with traditional AMT and conjunctival autograft (CAG) methods using glue or sutures, this approach not only reduces operative time, postoperative discomfort, postoperative visits, and topical steroids but also saves costs without compromising outcomes.
