Multimodel inference / Model averaging.

Akaike information criterion (AIC) and Akaike weights are reported for the 3 models (log-logistic, Weibull 1 and Weibull 2) analyzed through the 3 summarization strategies (mixed effects, meta-analysis and weighted regression). The estimates and model averaged estimates of the difference of the time for half-decrease of the level during recovery between patients with moderate and severe COPD (GOLD 4 vs. 2) are provided together with their associated standard error (SE).本研究针对采用3种汇总策略（混合效应、元分析与加权回归）分析的3种模型（对数逻辑斯蒂模型、威布尔1型与威布尔2型），报告了其赤池信息准则（Akaike information criterion, AIC）与赤池权重。同时提供了慢性阻塞性肺疾病（Chronic Obstructive Pulmonary Disease, COPD）GOLD 4级与2级患者在恢复过程中，其指标水平降低一半所需时间的差值的估计值、模型平均估计值，以及对应的标准误（standard error, SE）。
