Review in Der Ophthalmologe : Zeitschrift der Deutschen Ophthalmologischen Gesellschaft, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundSmartphone-based adapters for fundus photography offer a cost-effective alternative to traditional fundus cameras. The various offers vary widely in design, size, purchasing costs, user-friendliness, and image quality when compared to each other and to traditional fundus cameras.
objectiveThe aim is to enable the reader to understand the technical and optical aspects of fundus photography and therefore to evaluate the various offers of traditional fundus cameras and adaptors for smartphone-based fundus photography with respect to their personal requirements. MATERIAL AND
methodsThe technical and optical principles and aspects of fundus photography are explained and the various approaches to illumination, imaging, image capture and alignment are discussed. The association between field of view, pupil size, mydriasis and image quality are discussed as well as the challenges and difficulties of aligning the fundus camera relative to the patient's eye.
resultsThe most important technical aspects of a fundus camera are the avoidance of disturbing reflections when taking photographs, an acceptable field of view angle, the user-friendliness during alignment, success rate of imaging and the question whether mydriasis is necessary.
conclusionThe development of adapters for smartphone-based fundus photography has resulted in interesting offers, which make fundus photography available to a wider user spectrum at low purchase costs. The offers on the market vary widely. It is therefore difficult to reach a definitive evaluation; however, smartphone-based adapters mostly have limitations with respect to user-friendliness, the size of the field of view and image quality.
