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

purposeTo quantify retinal function longitudinally and cross-sectionally in patients with autosomal-recessive early-onset severe retinal dystrophy (EOSRD) associated with RPE65 mutations. SUBJECTS AND

methodsThe ocular phenotype was characterized in four children from three families up to the second decade of life, and in three siblings from one family aged 43-54 years carrying compound heterozygous or homozygous mutations in RPE65. Standard clinical examination included colour vision testing, fundus photography and Goldmann visual fields (GVF). Full-field ERGs (in all) and multifocal ERGs (in two patients) were also recorded. Visual performance and fundus appearance were compared to literature data.

resultsIn childhood, visual acuity (VA) ranged from 0.1 to 0.3, and GVF for target V4 was well preserved. VA and GVF were measurable in only one of the three adult siblings. Nystagmus was present in two of four children and two of three adults. Photophobia was absent in childhood and developed in adulthood. Funduscopic changes were discrete during the first decade of life in three of four children; one patient had clear macular changes already at age 5 years. All three adult siblings had distinct retinal changes including the macula. Bone spicules were not a feature. Residual colour vision was present in all patients with measurable VA. Rod ERGs were absent at any age; cone ERGs were detectable in early childhood. To date, VA data have been reported in 51 patients, visual fields in 29 patients, and a detailed fundus description in 34 patients. For all three parameters, data were comparable to the results in our patient cohort.

conclusionIn childhood, patients with RPE65 mutations have better visual functions than typically seen in Leber congenital amaurosis. The phenotype shows a common progressive pattern with intrafamilial and interfamilial variation. The data suggest a preserved retinal morphology at young ages, arguing for vision-restoring gene therapy trials in childhood.
