ALB and liver failure: We also failed to find any relationship between prothrombin activity, serum bilirubin, or serum albumin (as variables related to liver failure) and calcium deposits, but calcium deposits were more frequently observed among Child A patients (χ2 = 7.00; p = 0.03), especially when only cirrhotics were considered (χ2 = 9.00; p = 0.011).
