Coefficients from linear regression analyses assessing changes in measures of abortion among teenagers associated with implementation of a parental consent statute, Arkansas, 2001–2007

Measure	Minors vs. older teenagers^†	17- vs.18-year-olds
All abortions
Rate	1.59 (−2.13 to 5.32)	0.94 (−3.24 to 5.13)
Log of rate	0.02 (−0.28 to 0.32)	0.02 (−0.37 to 0.41)
Second-trimester abortions
Rate	0.59 (0.03–1.16)^*	0.02 (−0.76 to 0.80)
Log of rate	−0.03 (−0.46 to 0.41)	−0.11 (−0.70 to 0.47)

p<.05.

^†

Comparison is between 15–17-year-olds and 18–19-year-olds.

Notes: Each coefficient was derived from a separate regression. When the dependent variable is expressed in rates, coefficients represent the change in the number of abortions per 1,000 population; when it is expressed in logs, they represent relative change. Figures in parentheses are 95% confidence intervals.
