Mean Differences and Percent Change by Treatment Group at 4 and 12 Monthsa.

Abbreviations: SI, NIDA's Standard Intervention; WWE, SI plus Well Woman Exam; 4ES, SI, WWE plus four educational sessions.aValues represent differences and percentage change (parentheses) within groups from baseline. Due to rounding, calculations may not exactly reflect data from Table 1.bNumber of occasions used cocaine (number of days used * times per day); negative number indicates improvement.cNumber of episodes used cocaine per day; negative number indicates improvement.dNumber of days free from cocaine; positive number indicates improvement.eNumber of negative urine tests; positive number indicates improvement. We examined baseline and incremental data, but did not perform an incremental cost-effectiveness analysis on this outcome due to missing data.fProportion of participants abstaining from cocaine, past 30 days; positive number indicates improvement.gProportion of participants abstaining from cocaine, past 4 months; positive number indicates improvement.hTotal number of alcoholic drinks, past 7 days; negative number indicates improvement.iMean number of alcoholic drinks per day, of the days participants drank alcohol, past 7 days; negative number indicates improvement.jProportion of participants avoiding heavy drinking, past 7 days; “Heavy drinking” defined as ≥4 drinks per day of the days participants drank alcohol; positive number indicates improvement.kProportion of participants abstaining from alcohol, past 30 days; positive number indicates improvement.缩写说明：SI（Standard Intervention，美国国家药物滥用研究所[NIDA]标准干预方案）；WWE（Well Woman Exam，即SI联合女性健康检查）；4ES：SI联合WWE及四次教育课程。 注a：数值代表组内相较于基线的差值与变化百分比（括号内为百分比变化值）。因存在四舍五入，计算结果可能与表1的原始数据不完全一致。 注b：可卡因使用总频次=使用天数×每日使用次数；数值为负代表症状改善。 注c：每日可卡因使用发作次数；数值为负代表症状改善。 注d：可卡因戒断天数；数值为正代表症状改善。 注e：尿液检测阴性次数；数值为正代表症状改善。本研究分析了基线与增量数据，但因数据缺失，未针对该结局开展增量成本效益分析。 注f：过去30天内未使用可卡因的受试者占比；数值为正代表症状改善。 注g：过去4个月内未使用可卡因的受试者占比；数值为正代表症状改善。 注h：过去7天内的酒精饮品总摄入量；数值为负代表症状改善。 注i：过去7天内饮酒受试者的日均酒精饮品摄入量；数值为负代表症状改善。 注j：过去7天内未过量饮酒的受试者占比；“过量饮酒（Heavy drinking）”定义为饮酒日每日摄入≥4杯酒精饮品；数值为正代表症状改善。 注k：过去30天内戒酒的受试者占比；数值为正代表症状改善。
