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
Background and Aims: Ocular allergy (OA) constitutes a significant global public health concern, affecting an estimated 15% to 20% of the world's population, with approximately 40% of cases occurring in children. In Trinidad and Tobago (T&T), the risk of OA is notably heightened due to its geographical location and the recurrent exposure to Sahara dust. This study seeks to determine the prevalence of ocular allergy among secondary school students in T&T. Method: A descriptive cross-sectional study was conducted in a school-based setting from October 2022 to May 2023. Schools were selected for inclusion using a randomization process facilitated by an online spinner wheel tool. Data were collected using a modified version of the International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire. The questionnaire captured information on demographic characteristics, the presence of ocular allergy symptoms, associated risk factors, and the impact of ocular allergy. The data collected was analysed using the Statistical Package for Social Sciences (SPSS). The relationship between variables was assessed using Pearson Chi-square test, with a Results: A total of 420 students, aged 11-18 years, participated in the study, comprising 198 males (47.1%) and 222 females (52.9%). The overall prevalence of OA was 49.3% ( Conclusion: The prevalence of ocular allergy (OA) among secondary school students in T&T was relatively higher compared to findings from various studies conducted globally. This underscores the need for implementing effective strategies for early diagnosis and management to mitigate its impact.
