Ophthalmology
The Ophthalmic Statistics Group or OSG is led by Gabriela Czanner – Professor in Digital Health at The University of Southampton.
The OSG is a group of statisticians who have come together because of a common interest in ophthalmology. The group is open to members across the UK and beyond. The aspiration of the Ophthalmic Statistics Group is to “raise quality of statistics in ophthalmic publications”.
OSG achievements to date include:
- Development of Statistics Notes for the BJO – 14 ophthalmic statistics notes published
- Ophthalmic Statistics Workshops:
- Practical Ophthalmic Statistics Workshop held during the RCOphth Congress on 20th May 2015. Programme
- Ophthalmic Biostatistics workshop on 11th May 2015 in Liverpool. Programme
- Ophthalmic study design and approaches to statistical analysis – members of the OSG contributed to the event at the Royal College of Ophthalmologists on 9th February 2016
