统计学举例
• • We compared individual characteristics between firefighters and EMS workers, according to smoking status and arrival-time group, using Pearson's chi-square test, the Mann–Whitney test, Student's t-test, or analysis of variance, as appropriate. All reported P values are two-sided. We used linear mixed models8,9,10 to estimate weighted average values for FEV1 and percent of the predicted FEV1 for each 6-month period from March 12, 2000, to September 11, 2008, for all workers and separately for arrival-time groups and for firefighters and EMS workers. We also used the linear mixed models to assess changes during the first 6 and 12 months after 9/11, during the 7 years after 9/11, and during the 6 years between September 12, 2002, and September 11, 2008. We adjusted the FEV1 for age on 9/11, sex, height, and race and adjusted both the FEV1 and the percent of the predicted FEV1 for weight, smoking status, arrival time, and duration of work. The models allowed for the acute decrement in spirometric measurements that was previously observed in the first year after 9/11.2 We included all predictors in the models as fixed effects. We used a random intercept to take into account the heterogeneity across subjects and the correlation induced by having repeated observations on the same subjects. We performed a similar analysis with the last FEV1 value taken during the final 2 years of follow-up as the outcome but without the random effects. For white workers and black workers, at each 6-month interval, we used marginal logistic-regression models, fit with generalized estimating equations,11 to estimate the percentage of FEV1 values that fell below the lower limit of the normal range and the percentage that fell below 70% of the predicted value. Both the linear mixed models and the marginal logistic-regression models take into account that individuals could contribute unequal numbers of repeated correlated observations to the analyses over time. All data analyses were performed with the use of SAS software, version 9.1.

引言举例
• The terrorist attack on the world Trade Center on September 11, 2001 (hereafter referred to as 9/11), and its consequent collapse killed 2751 persons, including 343 rescue workers employed by the Fire Department of New York City (FDNY) and exposed thousands of persons to a dense, persistent dust cloud of pulverized building materials and chemical by-products of combustion or pyrolysis.1 The FDNY rescue workers who responded to the World Trade Center site during the collapse or the subsequent 10month rescue-and-recovery operations had substantial loss in pulmonary function during the first year after the event, more than 12 times the annual age-associated rate.2 The largest decline was observed among workers who arrived at the site on the morning of 9/11, and there were larger declines among firefighters than among emergency medical services (EMS) workers.2 Among non-FDNY rescue workers, volunteers, and residents of lower Manhattan who were exposed to World Trade Center dust, abnormal results on spirometry were common3,4 and persisted during a 3-year follow-up.3 However, health records were not available before 9/11 to determine the extent of new versus preexisting abnormalities. We investigated the longer-term consequences of exposure to World Trade Center dust by characterizing trends in pulmonary function during the 7 years after 9/11, as assessed by repeated measures of forced expiratory volume in 1 second (FEV1) among FDNY rescue workers.
