Table 1 PICO criteria for inclusion of studies

From: Surgical management, use and efficacy of adjuvant dyes in idiopathic epiretinal membranes: a systemic review with network meta-analysis

Population

Clinical cases, ≥ 18 years of age, with diagnosed idiopathic ERM who were surgically managed

Intervention

Surgical intervention (ERM removal) without ILM peeling

Comparator

Surgical intervention (ERM removal) with ILM peeling and/or any other interventions for ERM

Outcomes

Outcome measures

 Postoperative BCVA in logMAR at 6–12 months

 Recurrence rate at 1 year

 Efficacy of different transoperative adjuvants; for example, BBG, TB, ICG/IFCG, MBD

  1. BBG, Brilliant Blue G; BCVA, best-corrected visual acuity; ERM, epiretinal membrane; ILM, internal limiting membrane; ICG, indocyanine green; IFCG, infracyanine green; logMAR, logarithm of the minimum angle of resolution; MBD membrane blue-dual; PICO, population, intervention, comparator, outcomes; TB, trypan blue
