[Measurement of glaucoma-specific functionality with the GQL-15 and correlation with parameters of visual function].
Article in Der Ophthalmologe : Zeitschrift der Deutschen Ophthalmologischen Gesellschaft, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 papers, 1 of them a synthesis that pooled 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.
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
introductionGlaucoma is one of the leading causes of irreversible blindness worldwide and can have a significant impact on patient quality of life and vision-related functioning. The Glaucoma Quality of Life 15 (GQL-15) questionnaire is a disease-specific instrument to evaluate and quantify functional impairment of patients with glaucoma. This study evaluated the German version of the GQL-15 including correlations with perimetric parameters.
methodsA German version of the GQL-15 containing 15 items was developed and evaluated in 98 patients with glaucoma in different stages of the disease. The GQL-15 results were correlated with the perimetric parameters mean deviation (MD) and pattern standard deviation (PSD) of the better and worse eye. Classical and probabilistic test analyses (Rasch model) were performed.
resultsThe mean GQL-15 value was 77.3 ± 21.7 (SD) and most items of the GQL-15 correlated significantly with the MD of the worse eye (r = -0.416; p = 0.0014) and the better eye (r = -0.304; p = 0.02). There was also a highly significant correlation between glaucoma-specific QoL and visual acuity. A short version containing nine items yielding a higher psychometric performance can also be used.
conclusionsThe German version of the GQL-15 is a potent instrument to evaluate impairment in vision-specific functioning of patients with glaucoma. The GQL-15 values are better correlated with the sensitivity of the eye with the more severe glaucomatous damage. The data can help for a better understanding of individual patient impairment to improve medical advice and therapy of patients with glaucoma.
