Figure 2.

Placental lactogen and prolactin concentrations in maternal plasma samples collected from pregnant women at 20 weeks of gestation who went on to have babies of normal birth weight (control, n  = 40) or SGA (<5thcentile, n  = 10). One sample was removed from the control placental lactogen group as it was tested to be an outlier. Human placental lactogen P = 0.75, Student’s t-test. Human prolactin P = 0.30, Student’s t-test. Data shown as mean ± s.d.
