Ophthalmic Statistics Group’s BJO articles available online

22 February 2016

The Ophthalmic Statistics Group (OSG)

This network of medical statisticians, with a common interest in ophthalmic research, came together with a collective desire to raise statistical standards in ophthalmic research. They have held a number of events to engage with ophthalmologists and others involved in ophthalmic research starting with a workshop at the Annual Congress in 2015, and more recently the very successful seminar on study design and approaches to statistical analysis at The Royal College of Ophthalmologists, which proved so popular that it will most probably be repeated next year.

In 2013 The OSG were commissioned to write a set of statistical notes for the BJO, which provide an excellent description of some important considerations relating to the analysis and interpretation of ophthalmic data.
