Comparison of the incidence of placenta previa and placenta accreta spectrum disorder between women with a normal and short interpregnancy interval.

Placenta Previa	Normal IPI (n = 124)	Short IPI (n = 124)	χ^2	OR (95%CI)	-value
Placenta previa by USS			2.41	2.32 (0.78–6.88)	0.13
Present	5 (4.0%)	11 (8.9%)
Absent	119 (96.0%)	113 (91.1%)
Placenta previa by inspection			2.16	2.11 (0.76–5.81)	0.15
Present	6 (4.8%)	12 (9.7%)
Absent	118 (95.2%)	112(90.3%)
Placenta accreta spectrum disorder at delivery			0.34	2.02 (0.18–22.13)	0.57
Present	1 (0.8%)	2 (1.6%)
Absent	123 (99.2%)	122 (98.4%)

NB: USS = ultrasound scan, IPI = interpregnancy interval.
