Keratoconus in children in Tunisia: Epidemiological, clinical and therapeutic features.
Article in La Tunisie medicale, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 report the clinical and therapeutic particularities of pediatric keratoconus (KC).
methodsRetrospective study focusing on patients aged less than 18 years, presenting with KC and followed in a tertiary reference center in Sfax, Tunisia.
resultsOur study involved 38 eyes of 20 children. We found a mean age of 12.8 years, a family history of keratoconus for 25% of cases and an atopic background in 30% of children. The mean best-corrected visual acuity was 5.3/10, the mean myopia was -6.3D and the mean total astigmatism was -4.9D. The average maximum simulated keratometry (Kmax) was 54.6 D. The visual acuity decrease was correlated with the presence of corneal opacities, with all keratometric indices except Skewed Radial Axes (SRAX) at 3 and 5 mm, with all elevation parameters and those of pachymetry except the delocalization of the thinnest point. 71.1% of eyes were classified as clinical KC and 47% of eyes were classified as Amlser-Krumeich stage 4. 42.1% of eyes were fitted with glasses and 57.9% with contact lenses. Six patients (10 eyes) underwent cross-linking (CXL). We noted an evolution of the KC for 64.29% of eyes not treated with CXL and a stabilization of 80% of eyes treated with CXL. The difference in follow-up parameters between the two groups was significant.
conclusionPediatric KC is a severe disease, often diagnosed at a late stage. CXL is a safe and effective way to stop the disease.
