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
purposeKeratoconus presents certain peculiarities in pediatric patients when compared with adults. The greatest challenge in children is that the disease is more severe and faster in progression. In this retrospective study, we aimed to compare the accelerated and Dresden protocols for corneal crosslinking in patients aged <18 years who were followed-up for at least 12 months. Methods: A total of 36 eyes from 27 patients were included in the study. The best corrected and uncorrected visual acuity, maximal keratometry, corneal thickness, foveal thickness, and endothelial microscopy findings were evaluated at baseline and during the postoperative period at one, three, and six months. Thereafter, the patients were evaluated at one, three, six and twelve months postoperative. Corneal crosslinking was performed in all patients via the Dresden protocol (n=21 eyes) or the accelerated protocol (n=15 eyes). Data between the two groups were compared and XY statistical analysis was used.
resultsBoth protocols were effective in halting keratoconus progression. No patient had progression at the 12-month follow-up. A significant reduction in Kmax and improvement in the corrected distance visual acuity were observed only in the Dresden protocol group. Although the Dresden protocol was superior to the accelerated protocol in reducing Kmax (p=0.002), there was no significant difference in corrected distance visual acuity between the two groups.
conclusionThe accelerated protocol is as efficient as the Dresden protocol in stabilizing keratoconus progression. Although the Dresden protocol was superior to the accelerated protocol in reducing the Kmax, it did not produce better clinical results. Thus, the accelerated protocol is an efficient option. Furthermore, considering the advantages of reduced surgical time, the accelerated protocol is effective in halting keratoconus progression in the pediatric age group.
