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

purposePrimary congenital glaucoma (PCG), a severe form of glaucoma that presents early in life, is an autosomal recessive eye disorder that results from defects in anterior eye segment. Null mutations in LTBP2 were reported in patients with PCG in Pakistani and Iranian families. This study was aimed to identify the mutation profile of the LTBP2 gene in north Indian patients with PCG.

methodsAfter ethical clearance, 54 unrelated patients with PCG who were either negative or heterozygous for MYOC, CYP1B1, and FOXC1 mutations and 50 ethnically matched non-glaucomatous controls were recruited for the study. PCG diagnosis was established by the presence of buphthalmos in at least one affected eye and associated high intraocular pressure before the age of 3 years. LTBP2 was screened in genomic blood DNA for mutations, with PCR and direct sequencing of PCR amplified fragments.

resultsWe observed one intronic single nucleotide polymorphism (rs3742793) between exons 6 and 7 in the LTBP2 gene in 18 patients with PCG. This nucleotide change resulted in cytosine (C) being replaced by guanosine (G) at position g.75070493. No pathogenic variants were identified in the LTBP2 gene in our cohort of patients.

conclusionsLTBP2 gene mutations are not involved in the pathogenesis of primary congenital glaucoma in our patients. Thus, it is important to screen other glaucoma-associated loci and genes for involvement in congenital glaucoma in cases that are either negative or heterozygous for MYOC, CYP1B1, and FOXC1 mutations to have better insight into the disease pathogenesis.
