EVA = electric vacuum aspiration; RPOC = retained products of conception a Data are mean ± standard deviation, median (interquartile range [25–75 %], or n (%) unless otherwise specified. Percentage excludes patients with missing values. All P values are from Chi-Square test unless otherwise specified. d P value from Mann-Whitney U test. # Hysteroscopy = hysteroscopic morcellation or cold loop resection.
