从临床试验（n = 893）戒烟报告提交分层线性模型作为一个跨方法复制的异质性方法戒断测量，并澄清戒烟后的影响症状报告。五个个体差异参数挖掘不同方面的戒断推导出：截距（平均严重程度），线性斜率（方向和变化率），二次趋势（曲率），波动性（分散），并在lapsers，香烟系数（吸烟相关的偏转症状）。所有参数在人与人之间差异很大。断瘾者比戒酒者有更令人厌恶的症状模式，症状往往高于断瘾日的预测。这些结果强化了戒断症状高度可变的结论，并反对丢弃失败参与者的戒断数据。
Smoking withdrawal reports from a clinical trial (n = 893) were submitted to hierarchical linear modeling as a cross-method replication of a heterogeneity approach to withdrawal measurement and to clarify the influence of postcessation smoking on symptom reports. Five individual difference parameters tapping distinct facets of withdrawal were derived: intercepts (mean severity), linear slope (direction and rate of change), quadratic trend (curvature), volatility (scatter) and, among lapsers, a cigarette coefficient (smoking-related deflections of symptoms). All parameters were highly variable across persons. Lapsers had more aversive symptom patterns than abstainers, and symptoms tended to be higher than otherwise predicted on lapse days. These results reinforce the conclusion that withdrawal symptoms are highly variable and argue against discarding withdrawal data from participants who lapse.
