Fig 3.
The relationship between pRNFL, CST, MT and GC-IPL thickness with the duration of CKD.
The p-value was calculated by using spearman rank-order correlation coefficient. * p < 0.05 is statistically significant. Abbreviation: pRNFL = peripapillary retinal nerve fiber layer; MT = macular thickness; CST = central subfield thickness; NDCKD = non-diabetic chronic kidney disease; GC-IPL = ganglion cell-inner plexiform layer; r = spearman correlation coefficient.

The relationship between pRNFL, CST, MT and GC-IPL thickness with the eGFR.
The p-value was calculated by using spearman rank-order correlation coefficient. * p < 0.05 is statistically significant. Abbreviation: pRNFL = peripapillary retinal nerve fiber layer; MT = macular thickness; CST = central subfield thickness; GC-IPL = ganglion cell-inner plexiform layer; r = spearman correlation coefficient.
