Sensitivity Analysis With Regard to Spontaneous or Medically Indicated Preterm Birth

Outcomes	Spontaneous	Medically Indicated
CVD	1.47 [1.34, 1.62], n=2	1.88 [1.64, 2.16], n=2
CVD death	1.70 [1.47, 1.96], n=1	3.70 [2.88, 4.76], n=1
CHD	1.48 [1.36, 1.60], n=2	1.80 [1.62, 2.00], n=2
CHD death	2.12 [1.82, 2.45], n=2	3.56 [1.74, 7.25], n=2
Stroke	1.49 [1.24, 1.79], n=1	2.12 [1.70, 2.65], n=1

Data are risk ratio [95% confidence intervals], number of pooled studies. CHD indicates coronary heart disease; CVD, cardiovascular disease.
