Trends in paediatric visual impairment in England and Wales: a retrospective study (2009-2022).

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
introductionThe Certifications of Visual Impairment (VI) system was implemented to quantify and classify the incidence of visual impairment amongst the England and Wales population. This retrospective study investigates the trend in the certification of VI amongst children aged <16 years old.
methodsCVI data provided by the Certifications Office, was extracted and assessed to identify the various causes of mild-moderate (SI) and severe (SSI) visual impairment between 2009-2022. The data was classified into 11 broad groups which were similar in pathology. Incidence data was calculated using the official Census data. Byar's method was used to calculate confidence intervals to determine significant changes in the number of new registrations in 4 early intervals amongst conditions that recorded >5 registrations in every year or the study.
resultsBetween 2009-2022 there were 18,387 new registrations (10,915 SI and 7472 SSI). Disorders of the CNS (4145), retinal disorders (2990), and congenital abnormalities of the eye (4491) made up nearly 2/3 of the registrations. Amongst SI registrations, there was a significant increase in these 3 groups over the 13-year period excluding the first year of the Covid pandemic. However, there was a significant decrease in SSI registrations for congenital abnormalities.
conclusionsOverall, there is an increasing number of children registered SI/SSI in England and Wales. The main causes are: disorders of the CNS, retinal disorders and congenital abnormalities of the eye. This may be due to increasing awareness, early screening and advancements in genomic testing.
