The Swedish National Pediatric Cataract Register (PECARE): Coexisting systemic disorders 2007-2023.
Article in Acta ophthalmologica, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeTo analyse the frequency and type of coexisting systemic disorders in children operated on for cataract in Sweden.
methodsData were retrieved from the Swedish National Pediatric Cataract Register (PECARE) for children operated between January 1, 2007, and December 31, 2023 (n = 975), including follow-ups at age 1, 2, 5 and 10. Cataracts due to uveitis, trauma or radiation, and lens extraction due to luxation were excluded. Genetic screening was not mandatory during this period.
resultsOf the 872 children who remained after exclusions, 466 (53.4%) had unilateral cataracts and 406 (46.6%) had bilateral cataracts. Coexisting systemic disorders were found in 132/872 (15.1%), of which 5/132 (3.8%) were strongly suspected, 64/132 (48.5%) defined and 63/132 (47.7%) undefined. Overall, 20/872 (2.3%) were developmentally delayed without any systemic disorder diagnosis. Systemic disorder was present in 20/466 (4.3%) with unilateral cataracts, 112/406 (27.6%) with bilateral cataracts, 22/138 (15.9%) with bilateral inherited cataracts and 11/32 (34.4%) with parental consanguinity.
conclusionCoexisting systemic disorders were present regardless of laterality, but more common among children with bilateral cataracts. Prevalence was similar among children with consanguineous parents, and lower among children with hereditary cataracts. National consensus regarding genetic screening for systemic disorders is needed.
