ALB and diabetes mellitus: Omitting of evaluation of initial lab test (e.g., initial hemoglobin, total proteinemia, and level of albumin) is also gross limitation of our study, but we did not have sufficient data set to assessed covariates such as significant comorbidities (e.g., chronic liver disease, chronic renal dysfunction, chronic obstructive pulmonary disease, diabetes, chronic heart failure), age and sex that all could be associated with change in haemoglobin and albumin regardless of primary pelvic ring injury.
