Sociodemographic and clinical characteristics of keratoconus: multi-centric study from India.

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
objectivesThis study aimed to determine if the sociodemographic and clinical characteristics of patients with keratoconus had changed in recent times.
methodsThis prospective multicentre study was conducted at four tertiary eye institutes in India between October 2022 and September 2023. Only patients newly diagnosed with keratoconus were included in the study.
resultsThe mean age of the 421 patients was 23.5 ± 8.9 years, and there were 249 (59.1%) male and 170 (40.9%) female patients. The highest prevalence (44.89%) was observed between the ages of 20 and 29. Females were younger than males (P = 0.040). The onset of symptoms preceded the diagnosis by 2.7 ± 4.3 years. A total of 298 patients (70.8%) were from the urban areas. The majority of patients (79.1%) belonged to the middle socioeconomic class (P < 0.001), and 251 (59.6%) had obtained a graduate or higher degree (P < 0.001). The most common sign in mild keratoconus was scissors reflex. Binocular vision impairment was absent in 259 patients (61.5%), whereas the rest had some degree of impairment. Keratoconus was asymmetrical in 36.1% of the patients. Clinical signs were absent in 5% of the patients.
conclusionDespite advances in corneal imaging and awareness about keratoconus, patients were still being diagnosed in the third decade of life. The presence of scissors reflex in patients coming for refraction should alert eyecare professionals to the presence of keratoconus, and corneal tomography should be advised in these patients.
