Abstract: 
Survival analysis has become one of the most common statistical techniques 
for analyzing longitudinal data in the social sciences, largely due to its 
ability to produce unbiased estimates in the presence of censored or 
incomplete data. A follow-up case record review of subjects (N=175) in a 
recent experimental study provides the opportunity to revisit original 
survival estimates and compare them to estimates generated using nearly 
complete data. Results indicate that Kaplan-Meier median estimates of 
survival time and parameter estimates using Cox Proportional Hazards 
Regression were relatively accurate despite differential censoring between 
the treatment and control groups. Estimated mean averages tended to be 
inaccurate in the presence of substantial censoring. Implications for 
research and practice are discussed. (c) 2005 Elsevier Ltd. All rights
