Random effects meta-analyses were conducted for the thickness of retinal parameters, at both disc and macula: Retinal nerve fibre layer (RNFL), ganglion cell layer (GCL), inner plexiform layer (IPL), ganglion cell-inner plexiform layer (GCIPL), choroid thickness (CT), macular thickness (MT) and macular volume (MV). The Newcastle-Ottawa Scale was used for risk of bias (RoB) assessment. Publication bias, sensitivity analysis and certainty of evidence (CoE) was assessed using Doi plots, the leave-one-out method and the GRADE approach, respectively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Of the 2,416 records screened, eight studies (\n                      <jats:italic>n<\/jats:italic>\n                      = AUD = 6,276 eyes; HC = 2,695 eyes) were included in meta-analyses.
