  1. The results are expressed as Mean ± SD. Statistical significance was determined by non-paired, two tails Mann–Whitney test. *P < 0.05, **P < 0.01 or less compared with gallstone group; + P < 0.05, ++ P < 0.01 or less, compared with tumor group. Significance was also found when gallstone + other benign diseases (G + O) was compared with tumour + PSC (T + PSC) for NPP7 and ALP, either per ml or per mg.
