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

purposeRefractive error (RE) is one of the most common ocular disorders among children worldwide. This study aimed to investigate the prevalence of RE and possible risk factors among school children in Riyadh.

methodsThis is a cross-sectional study using data collected at various schools. To achieve the aim of the study, we selected a random sample of 850 school children aged 6-15 years. The examination was based on the RESC protocol and included full visual assessment. Furthermore, a questionnaire was sent to the parents of the participants to ascertain information about lifestyle factors. We constructed a logistic regression model to evaluate the predictors of RE.

resultsClose to a third of the children had a RE. Of those identified as having the condition, 60% did not wear glasses (newly diagnosed). Nearly all the children (95.4%) in our sample reported using electronic devices, according to parents. No association was found between using electronic devices and having a RE (

conclusionWe found a higher prevalence of uncorrected RE than previously reported in other Saudi studies. About 60% of children who had RE were not wearing glasses, highlighting the need for a standardized school screening program for early detection and management. Outdoor activities were associated with a lower likelihood of having a RE. These findings might support initiatives to encourage outdoor activities among school children.
