Side effects of proton beam therapy of choroidal melanoma in dependence of the dose to the optic disc and the irradiated length of the optic nerve.
Article in Graefe's archive for clinical and experimental ophthalmology = Albrecht von Graefes Archiv fur klinische und experimentelle Ophthalmologie, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 2 of them syntheses 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
purposeTo analyze the impact of the dose to the optic disc and the irradiated length of the optic nerve on radiation-induced optic neuropathy, radiation-induced retinopathy, iris neovascularization, secondary glaucoma, enucleation, and local tumor control after proton beam therapy (PBT) of choroidal melanoma.
methodRetrospective analysis of 1129 patients, who received primary PBT for the treatment of choroidal melanoma with a dose of 60 cobalt gray equivalents (CGE) between 1998 and 2013 at the Helmholtz-Zentrum Berlin, Germany. Kaplan-Meier curves and logrank test have been used for time-to-event analyses. Adjustment for potential confounders was done using multiple Cox regression models with forward and backward selection.
resultsWe found a significant correlation between the irradiated length of the optic nerve and the dose to the optic disc (correlation coefficient, 0.93). Multivariate Cox regression revealed the dose to the optic disc as an independent predictive risk factor for the development of radiation-induced optic neuropathy (p < 0.001, HR 1.023, 95 CI 1.016-1.029), iris neovascularization (p < 0.001, HR 1.013, 95% CI 1.008-1.019), secondary glaucoma (p < 0.001, HR 1.017, 95% CI: 1.011-1.023) and enucleation (p < 0.001, HR 1.037, 95% CI 1.020-1.053). The irradiated length of the optic nerve was not a statistically independent predictive risk factor in multivariate analysis.
conclusionOur data implicate the predominance of the dose to the optic disc over the irradiated length of the optic nerve regarding radiation-induced optic neuropathy, iris neovascularization, secondary glaucoma, and enucleation.
