Pearson's correlation coefficient analyses of the concentration and total amount of Hb with periodontal clinical parameters. (a) Concentration and total amount of Hb with the number of bleeding sites. (b) Concentration and total amount of Hb with number of periodontal pockets ≥4 mm. (c) Concentration and total amount of Hb with number of deep pockets ≥6 mm. (d) Concentration and total amount of Hb with number of bleeding pockets ≥4 mm. (e) Concentration and total amount of Hb with number of bleeding pockets ≥6 mm. Each point denotes a subject in the population (n = 408); r, correlation coefficient
