Analysis of intra- and inter-observer error
SMI findings in pathological placentas were used to calculate the
inter-observer agreement. An inter-observer error was determined by
examining the four types of findings between the two examiners (NF and
JH) in 22 findings. Additionally, an inspector (NF) evaluated the
findings of 22 places as 4 types of findings twice at intervals, and
calculated the intra-observer error.
