Conjunctival goblet cell density The goblet cell density, for the oral uridine treatment group, at 1 and 3-months increased; however, the differences were not significant at 1 month ( P =0.660, Wilcoxon signed rank test) and showed only marginal significance at 3-months ( P =0.053, Wilcoxon signed rank test) ( Fig. 1C ).
