Trial profile

SLT=selective laser trabeculoplasty. *Two patients were randomised twice due to computer failure: one was initially randomised to medication but was subsequently randomised to, and received, SLT. The other was initially randomised to SLT but was subsequently randomised to, and received, medication. These patients are included in the figure according to their second randomisations. In addition, four other patients who did not meet the eligibility criteria (and could not receive treatment) were randomised in error. These patients were subsequently removed from the study and are not included in the total randomised.
