SURVIVAL DISTRIBUTION COMPARISON AND SURVIVAL ESTIMATION OF SOCIO-ECONOMIC AND LABORATORY VARIABLES

Abstract

Objectives: The objective of this study is to compare and analyze the survival
distributions of the different categories of the socio-economic and laboratory variables of the
ESRD patients. Through which we can see the difference between the categories of the individual
categorical variable with respect to the survival distributions. Data Sources: The sample of 40
patients was taken from the two hospitals of Lahore city. Jinnah Hospital Lahore. Lahore General
Hospital, Lahore. Design of the Study: The sample methodology of the study is the convenience
6 sampling . Data Collection: The questionnaire was used to collect the primary data from the
patients. Period of the Study: All the patients were followed up during the study duration of 122
days. Materials and Methods: To examine the significant difference in the different categories of
the socio-economic and laboratory variables with respect to the survival distribution the Kaplan-
Meier method is used. To illustrate the survival distributions the survival curve and hazard curve
2 were used . Results: All the p-values of socio-economic and laboratory are very large except the
p-value of the Serum Albumin which is very small and less than 0.05 level of significance. The
categories of all the laboratory variables were classified into “Normal values Range” and “Other
values out of range values”. The categories of the Serum Albumin are significantly different.
Conclusions: It is concluded that the survival distributions of all the categorical variables are
equal and do not differ significantly. Furthermore the laboratory variable Serum Albumin is
2 significantly differing by the log rank test . So it is clear indication that the serum albumin is not the
status variable of nutrition.
