Table 1. Changes in BW, MAP, serum Na and K concentrations, and urine output before LCC diagnosis, at the onset of LCC symptoms, and after LCC diagnosis.

Abbreviations: BW, body weight; LCC, late-onset circulatory collapse; MAP, mean arterial pressure.
a
The day of measurement of each parameter was calculated by considering the day of the onset of LCC symptoms as 0. The period between each of these intervals was measured in days. Medians and ranges are shown.
b
BW increase rate was calculated by considering the body weight before LCC diagnosis as standard.
c
P<0.05 compared with before LCC diagnosis.
d
P<0.05 compared with onset of LCC symptoms.
Data are represented as mean±s.d.
