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
purposeReview Pattern Electroretinogram (PERG) data from a pediatric population to characterize the development of response.
methodsA case review of 104 subjects who had PERG aged between 0 and 9 years of age as part of routine clinical testing who were categorized as normal. PERG responses were recorded with skin electrodes, with the stimulus presented on a 40
resultsAn increase in P50 amplitude was noted over the first 2 years of life, a less rapid increase in amplitude was observed after this. The P50 timing was noted to decrease in the first 6 months but stabilized after this. A similar increase in amplitude was observed for the N95 amplitude with a modest decrease in latency.
conclusionThis study has shown an increase in PERG amplitude beyond the first 6 months of life with the most rapid rate of increase of response occurring in the first 2 years. This physiological data potentially documents the functional maturation of the human macula that parallels the anatomical changes noted via histology. KEY MESSAGES: Robust PERG responses are possible in pediatric cases recorded with skin electrode to widefield stimuli, even in young infants. Paper provides evidence of physiological development of macula that correlates well with previously documented anatomical maturation.
