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
objectiveThis study investigated the efficacy of corneal neurotization (CN) surgery for treating neurotrophic keratitis (NK) and evaluated potential factors affecting treatment outcomes.
methodsLiterature databases were searched from the inception to January 2024 for retrospective or prospective studies related to corneal neurotization for NK treatment. Data analysis was performed using SPSS 26.0, including analysis of variance, rank sum tests, and multiple regression analysis to determine the efficacy of CN and the impact of patients' age, gender, surgical method, and etiology on surgical outcomes.
resultsA total of 14 retrospective or prospective studies were included, comprising 191 patients who underwent CN for neurotrophic corneal lesions. CN significantly improved Mackie staging, logMAR visual acuity, and corneal sensation in patients with congenital and acquired NK (p < 0.0001). In young patients (≤ 30 years), improvement in central corneal sensation was more pronounced (p < 0.05), while elder patients (> 30 years) showed more significant visual acuity improvement (p < 0.05). Multiple linear regression analysis also showed that age was associated with the postoperative improvement in logMAR visual acuity: the elder the patients, the more improvement in visual acuity (p < 0.05). Compared to direct corneal neurotization (DCN), indirect corneal neurotization (ICN) showed more significant improvement in central corneal sensation (p < 0.01). And the patients with congenital NK got more improvement of central corneal sensation after CN by comparison with the others with acquired etiologies (p < 0.001). Multiple linear regression analysis suggested that congenital etiology was associated with more significant postoperative improvement in corneal sensation (p < 0.05).
conclusionCN surgery significantly improves visual acuity, NK Mackie staging, and corneal sensation in NK patients. Age, etiology, and surgical technique may significantly influence treatment outcomes.
