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
purposeCongenital ectopia lentis (CEL) and heart abnormalities are common clinical symptoms in patients with Marfan syndrome (MFS) and related fibrillinopathies, which is caused by mutations in fibrillin-1 (FBN1) gene. This study aims to explore the ocular and cardiovascular characteristics and their association with genotype in children with MFS and related fibrillinopathies.
methodsSeventy-nine children diagnosed with CEL and with FBN1 mutations confirmed via whole-exome sequencing were included for genotypes and phenotypes analysis. The axial length (AL), corneal curvature, and refractive status were included for ocular phenotypes analysis. The cardiovascular examination was performed by echocardiography, and aortic root Z score was calculated to evaluate the severity of aortic dilatation. The heart disorders were classified as aortic root dilatation, valvular disorders, and others. Both the ocular and cardiac manifestations were collected for comprehensive analysis and compared among patients with different genotypes, including the mutation involving cysteine substitution or mutation in different regions.
resultsIn CEL children with FBN1 mutations, 77.2% patients could be diagnosed as MFS. It was observed that children with mutations in exons 22-42 had significant higher aortic root Z score (P = 0.003) and higher incidence of cardiovascular disorders (P = 0.004). Additionally, children with cysteine substitution mutations had significant higher aortic root Z score (P = 0.011), and the aortic root Z score was positively associated with axial length (AL) in children under 6 years old (P = 0.035). Those with long AL (≥ 26 mm) had significant higher incidence of valve disorders (P = 0.023). In addition, nearly half the children with CEL (46.8%) were diagnosed with cardiovascular disease for the first time.
conclusionsCEL children with FBN1 mutations involving cysteine substitution or mutations in exons 22-42 or with long AL had higher risks of severe cardiovascular complications. Knowing the phenotype may help in anticipating severe cardiovascular disease in CEL patients.
