aPUUV, Puumala virus; mild and severe acute renal failure was defined as serum creatinine <620 μmol/L and >620 μmol/L, respectively; ALT, alanine aminotransferase.
bOf all parameters, only thrombocytopenia predicted subsequent severe renal failure. Medians (range) and actual number of patients are given.
cn.s., not significant.
dMann-Whitney U test.
eFisher exact test.
