Delaying the Onset of Nearsightedness Until Treatment (DONUT) Clinical Trial (DONUT)
The aims of this clinical trial will test whether or not the onset of nearsightedness is delayed in a group of children randomized to nightly drops in 0.05% atropine in both eyes, in comparison to children who receiving nightly placebo drops in both eyes. The primary outcome is the two-year cumulative incidence of nearsightedness. The second aim of this project will determine whether atropine is associated with slower eye growth in children receiving nightly drops of atropine versus placebo.

Detaillierte Beschreibung
The "Delaying the Onset of Nearsightedness (DONUT) Study - Data Coordinating Center" is a randomized clinical trial designed to compare the effectiveness 0.05% atropine and a placebo in delaying the onset of nearsightedness. It is a multicenter (14 clinic centers) randomized clinical trial of 606 children (recruited over two years) ages 6 to 11 years who are determine to be at high risk of myopia onset, as measured by cycloplegic autorefraction and age. The primary outcome is the two-year cumulative incidence of myopia. The second aim of this project will determine whether atropine is associated with slower axial elongation in children receiving nightly drops of atropine versus placebo.
Participants will be seen every six months for at least two years to determine the onset of myopia.

Plan für individuelle Teilnehmerdaten (IPD)
Planen Sie, individuelle Teilnehmerdaten (IPD) zu teilen?
Beschreibung des IPD-Plans
The final dataset to be shared will include self-reported demographic and participant activity and compliance to treatment data from interviews with participants' parent or guardian, eye examination data, and refraction data. The investigators will share de-identified individual-participant level (IPD) data. Appropriate measures such as providing only participant age and not providing clinical site of data collection will be used for data de-identification and sharing, and informed consent forms will reflect those plans. Calculated fields, rather than the component fields, will be available for a more accessible dataset.
IPD-Sharing-Zeitrahmen
Shared data generated from this project will be made available as soon as possible, and no later than the time of publication or the end of the funding period, whichever comes first. The duration of preservation and sharing of the data will be a minimum of 10 years after the contribution of the data to Vivli.
IPD-Sharing-Zugriffskriterien
Data will be available for access on Vivli.
