Demographic and Clinical Characteristics of Patients with Corneal Ectasia at Multiple Medical Centers in Saudi Arabia: A Hospital-based Study.
Article in Oman medical journal, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Objectives: We sought to explore the clinical characteristics of corneal ectasia and provide insights on related factors, including demography, ocular health, and the management trends in the Saudi population. Methods: We conducted a retrospective hospital-based chart review of patients with corneal ectasia in multiple medical centers in Saudi Arabia between 1 January and 31 December 2018. Eye care professionals diagnosed these patients based on their medical history, physical examination, and the use of Pentacam. The severity of the condition was assessed using the k median index from the Pentacam map following the modified Krumeich grading system. Results: We reviewed the medical records of 430 eyes of 215 patients with corneal ectasia. The majority (98.6%) of patients had bilateral corneal ectasia, with 202 (94.0%) having keratoconus and 13 (6.0%) having post-laser in situ keratomileusis ectasia. Males and age groups between 14 and 45 years were more affected. The mean age of onset was 7.1 years, ranging from 2-32 years, which was higher among patients from the western region. Regarding severity, 230 (53.5%) eyes presented in the initial stages, while 36 (8.4%) were in the severe stage with no significant difference between the regions studied. No significant differences were observed in mean central corneal thickness and power between patients from the central and western regions. Corneal rigid gas permeable contact lens was most used in treatment of 176 (40.9%) eyes followed by glasses in155 (36. 0%), while corneal cross-linking was the common surgical intervention (10.9%), followed by penetrating keratoplasty (3.0%). Conclusions: Most keratoconus patients had a bilateral mild stage of the disease and were in their third decade. This high rate of bilaterality of diseases during diagnosis may be due to misdiagnosis in the initial stages, which highlights the importance of community and eye care professionals' awareness of comprehensive eye examinations and regular follow-up, including corneal topography assessments of both eyes.
