Visual Evoked Potentials in Operated Primary Congenital Glaucoma: A Cross-Sectional Comparative Study.
Article in Clinical ophthalmology (Auckland, N.Z.), 2021. 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
backgroundTo evaluate the VEP parameters in operated controlled primary congenital glaucoma (PCG) eyes and compare them to normal age similar children eyes.
methodsA cross-sectional comparative study conducted on 34 (19 right) eyes of 26 (19 males) children operated for PCG and 30 (17 right) eyes of 22 (12 males) age similar control children in a university-based practice. All study participants were subjected to a standard protocol of examination and electrophysiological testing (single flash VEP response, light adapted, pupils not dilated), reporting on the P2 implicit time, N1-P1 and N2-P2 (amplitude).
resultsThe mean±SD of the age of the study children and controls was 43.22±33.2 and 55.68±35.2 months respectively (p=0.217). The mean±SD IOP and cup/disc ratio of the study children were 18.4±5.2 and 5.2±3.3mmHg and 0.7±0.2 and 0.3±0.3 at presentation and at testing, respectively. The VEP testing was conducted after 21.5±21.3 months of surgery for PCG. There was no statistically significant differences in P2, N1-P1 and N2-P2 between patients and controls (p=0.941, 0.916,0.945, respectively). There was no statistically significant correlation between most of the clinical characteristics of the study eyes and any of the studied VEP parameters.
conclusionOperated controlled PCG eyes have VEP parameters that match their normal fellow children.
