From: Adverse Effects of fine particulate matter on human kidney functioning: a systematic review
Schematic overview of the distribution of articles on kidney disease (outcomes) in the systematic review. Eligible articles (n = 40) were divided into the corresponding disease outcomes. Included studies focused on (i) clinical measurements of eGFR (n = 8), (ii) biomarkers to evaluate kidney function following PM exposure (n = 2), (iii) glomerular diseases (n = 4), (iv) diabetes mellitus as a driver to kidney function decline (n = 2), (v) CKD (n = 14), (vi) ESRD (n = 2), (vii) kidney failure (n = 4), and (viii) kidney transplantation (n = 4). These numbers of articles for the listed classes of kidney disease (outcomes) do not necessarily correspond with the main text, as for each class, the most representative articles were considered. Abbreviations: CKD, chronic kidney disease; ESRD, end-stage renal disease; eGFR, estimated glomerular filtration rate; PM2.5, fine particulate matter (< 2.5 microns)
