Change in the Percent of Tooth Sites with a Probing Depth >= 4mm versus Change in the Serum Biomarker. A negative value on the horizontal axis indicates a reduction, or improvement, in the percentage of tooth sites with probing depths >= 4mm. A negative value on the vertical axis indicates a reduction in the biomarker level from baseline to 29–32 weeks. X’s denote treatment group participants, dots denote controls. The blue line is the regression slope for treatment group women; the red line is for controls. See text for P values.
