We compared patients who were offered surgery (cholecystectomy) to those who were not offered surgery (Table 4), and discovered that the surgery group was younger (P = 0.040), had a longer follow up period (P = 0.026), had a higher albumin level (P = 0.001), had less cardiac comorbidity (P = 0.001), had a lower ASA score (P = 0.001), had less acute kidney injury (AKI) at presentation (P = 0.002), lower CCI score (P = 0.001) and had fewer mortalities during follow up time (P = 0.001). This evidence concerns the gene ALB and acute kidney injury.
