1 · What the graph read from it

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.

2 · The registry

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

Background: Keratoconus (KC) is the most common form of keratectasia that is associated with impaired vision and reduced quality of life, especially in adolescents. This study aims to identify and assess the risk factors associated with KC among high school students in Trinidad and Tobago (T&T). Method: This was an institutional-based, cross-sectional study that utilized the Keratoconus (KC) Risk Investigative (KRIS) questionnaire to assess risk factors of KC among high school students in T&T. A multistage stratified cluster sampling technique was employed. The study examined established and non-established risk factors. Results: A total of 2084 students (mean age: 14 years, SD = 1.6, range 11-20) participated, with 674 (32.3%) reporting at least one risk factor of KC. The most prevalent risk factor overall was prolonged near-work (≥ 8 h/day, 59.8%), while exposure to sunlight (25%) was identified as the most established risk factor. Of those with risk factors, 60 (2.9%) had KC which was significantly associated with family history ( Conclusion: This study underscores the role of genetic and environmental factors in KC development, highlighting the importance of near-work and light hypersensitivity. Early screening and targeted interventions are recommended, especially for individuals with a family history or related atopic conditions.
