Fig. 1 — Microvascular outcome parameters before and after bariatric surgery. Figure 1 depicts significant improvements in the CNFD, CNBD and CNFL from baseline to 12 months after bariatric surgery. There were also significant reductions in the eGFR, serum creatinine and a change in uACR (non-significant). a Corneal confocal microscopy. a (i) Corneal nerve fibre density before and after surgery, (ii) corneal nerve branch density before and after surgery, (iii) corneal nerve fibre length before and after surgery. b Renal parameters. b (i) urinary albumin/creatinine ratio before and after surgery, (ii) estimated glomerular filtration rate before and after surgery, (iii) serum creatinine before and after surgery. CNFD, corneal nerve fibre density; CNBD, corneal nerve branch density; CNFL, corneal nerve fibre length; uACR, urinary albumin/creatinine ration; eGFR, estimated glomerular filtration rate; sCreat, serum creatinine
