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
aimTo evaluate the clinical efficacy and feasibility of superficial corneal opacities treated by excimer laser phototherapeutic keratectomy (PTK) combined with small incision lenticule extraction (SMILE)-derived corneal stromal lenticule transplantation.
methodsA retrospective interventional case series of nine patients aged 12-59y with superficial corneal opacity caused by different pathologies who underwent standardized PTK combined with SMILE-derived corneal stromal lenticule transplantation was examined. Lenticule patches were fixed with fibrin glue. All patients underwent pre- and post-operative clinical assessments at different times for up to 12mo. Slit lamp microscopy, corneal density, uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), and anterior segment optical coherence tomography (AS-OCT) were examined.
resultsThe patients' mean age was 36.00±5.80 (12-59)y. Seven eyes (77.8%) gained UDVA and CDVA at the last measurement compared to their preoperative levels. The densities of the total cornea, the total anterior corneal layer, and the anterior corneal layers of 0-2 and 2-6 mm decreased significantly by 12.4%, 27.5%, 46.7%, and 32.8%, respectively. After human allogeneic transplantation, the implanted lenticules of all eyes were clearly visible by AS-OCT and remained transparent without displacement or graft rejection. The thickness of the central cornea and corneal lenticule transplants were stable throughout the entire postoperative period. One case experienced the postoperative complication of delayed corneal epithelial healing.
conclusionPTK combined with SMILE-derived corneal lenticule transplantation improves long-term visual acuity. Therefore, it is a new, safe, and effective method for treating superficial corneal opacity.
