Clinical study on the effect of multifocal contact lenses on myopia progression in myopia school children : Multifocal contact lens study for suppression of myopia progression.
Trial report in Trials, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundThe efficacy of peripheral low add multifocal soft contact lenses (SCLs) for suppressing the progression of myopia is controversial. The aim of the on-going present clinical study is to investigate whether or not multifocal SCLs with + 0.50 diopters (D) addition suppress the progression of myopia in myopic elementary school children.
designProspective randomized controlled trial. SUBJECTS AND
methodsThe study plans to include a total of 100 myopic school children. Target subjects are primary school male and female students with mild to moderate myopia. Children who have eye-related diseases other than myopia are excluded from the study, because they may affect the evaluation of the outcome. Subjects will be randomly assigned to wear daily disposable multifocal contact lenses with + 0.50D addition or daily disposable SCLs. Subjects will wear contact lenses on both eyes and will be observed for 2 years under a double-masked examination. Primary outcome is a change in the axial length over the 2-year period.
objectivesThe purpose of this study is to identify whether or not multifocal SCLs with + 0.5D addition suppress the progression of myopia in myopic elementary school children as compared with standard SCLs.
