Hi,
Following are the papers we like to extract data from:
1) Arshinoff, S.A., Y.N.J. Strube, and R. Yagev, Simultaneous bilateral cataract surgery. Journal of Cataract & Refractive Surgery, 2003. 29(7): p. 1281-1291.
2) Acosta-Rojas, E.R., et al., Association Between Visual Impairment and Patient-Reported Visual Disability at Different Stages of Cataract Surgery. Ophthalmic Epidemiology, 2006. 13(5): p. 299-307.
3) Alfonso, J.F., et al., Visual acuity comparison of 2 models of bifocal aspheric intraocular lenses. Journal of Cataract & Refractive Surgery, 2009. 35(4): p. 672-676.
the last paper compares 2 lens. my question is: in the paper they have mentioned baseline (before surgery) characteristics of patients and after surgery (outcomes). In EPPI, they have option of outcome but how to input the baseline characteristics?
