Total pore area (TPA) (mm2/mm2), total pore number (TPN) (mm−2), and average pore area (APA) (mm2) were calculated for each layer. TPA and TPN were normalized by the area of each layer. All values are reported as the average across all slices. Data are expressed as unadjusted means ± SD.
Significant p values are highlighted in bold
