Fig. 4

Line graphs of changes in serum creatinine levels in follow-up patients. Changes in serum creatinine (SCRN) levels in follow-up Becker muscular dystrophy (BMD) group with (a) undeteriorated motor function, or (b) deteriorated motor function and in follow-up Duchenne muscular dystrophy (DMD) group with (c) undeteriorated motor function, or (d) deteriorated motor function. A point denotes a record in a patient and the points linked by a line belong to the same patient. Increased Vignos or Brooke scores denote deteriorated motor function. The color of point refers to the glucocorticoid administration status: blue and red points denote no glucocorticoid administration and glucocorticoid administration, respectively. Graphs (a, c, and d) are split into two parts to decrease the overlap of points, and the graphs are thus more readable
