From: Clinical utility of chitotriosidase enzyme activity in nephropathic cystinosis
Correlation of plasma chitotriosidase activity with WBC cystine assay in 32 cystinotic patients, 22 Europeans (◊) and 10 Egyptians (◊), all on different doses of cysteamine therapy. Four treated Egyptian patients were not sampled for WBC cystine at the same time of the chitotriosidase sampling, so they were not included in the analysis. Pearson correlation coefficient was used.
