Changes in creatinine (Cr) levels according to period of exposure to organic solvents and lapse of time; Dots on the line indicate time points when Cr levels were measured. The first and second measurements of Cr levels were made in February 1997 and May 1999, when the patient was 38 and 40 years old, respectively. Cr levels were measured every 6–12 months after 1999, every 2 months starting in 2007 (when the patient was 48 years old), and every month starting in 2008 (when the patient was 49 years old)
