Figure 1. From: Effects of Smoking Cessation with Voucher-Based Contingency Management on Birth Outcomes.

Upper panel shows 7-day point-prevalence smoking abstinence in the contingent (open bar) and noncontingent (closed bar) treatment conditions at end-of-pregnancy assessment (upper panel). Treatment conditions differed significantly (P = .001). Bottom panel shows mean percent of all antepartum smoking-status tests that were negative for recent smoking in each treatment condition. Brackets represent 1 ± SEM. Treatment conditions differed significantly (P < .0001).

Figure 2. From: Effects of Smoking Cessation with Voucher-Based Contingency Management on Birth Outcomes.

Birth weights of infants born to mothers treated in the contingent (left column) and noncontingent (right column) treatment conditions. Each symbol represents an individual infant’s birth weight and the solid line in each column represents the least square mean weight for that condition. The dashed line demarcates the 2500 g cutoff for low birth weight. Mean birth weight differed significantly between treatment conditions (P = .03) as did the percent of low birth weight deliveries (P = .02).
