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
Purpose: Surgery is the definitive treatment for pterygium; therefore, reliable animal models are required for translational research. The goal of this investigation was to establish a standardized preclinical model of pterygium-like lesion. Methods: A subconjunctival injection of fibroblasts (NIH3T3) and extracellular matrix was administered to 22 New Zealand rabbits. Clinical evaluation was assessed at different points, the severity of the lesion was scored according to four grades and correlated with the area of hyperemia and the histopathological findings on day 23. Results: Thirteen of 22 eyes (60%) developed pterygium-like lesions after 7 days and progressed through different grades. Initially, grade 3, characterized by an elevated and fleshiness conjunctiva with tortuous hyperemia, was evident on day 7. By day 15, lesion decreased to grade 2, with less elevation and hyperemia. Subsequent improvement was noted, with grade 1 on day 18. Finally, day 23 was marked by a white‒yellow lesion, classified as grade 4. The area of hyperemia increased from grade 2 to grade 3 (P < 0.05) and decreased from grade 3 to grade 4 (P ≤ 0.05). Histopathological analysis revealed a tendency toward increasing inflammation at grades 2, 3, and 4. There was a correlation between clinical features and the degree of inflammation. Conclusions: Subconjunctival injection of NIH3T3 and extracellular matrix induces a pterygium-like lesion that progresses across four grades, beginning with an acute inflammatory process that evolve a chronic form. This study provides a replicable model for simulating pterygium. Translational Relevance: The development of a standardized preclinical model of pterygium to evaluate new pharmacological or surgical treatments.
