Preliminary Data Analysis
In this chapter we describe the preliminary data an
alysis of CKD among gout patients
in Nongjik hospital, Pattani Province between Janua
ry 2004 and December 2010.
There were three sections in this chapter: variable
s of interest, frequency distribution
of determinants and the association between the out
come and determinants.
3.1 Variables of interest
The roles of the variables classified as determinan
t and outcome. These variables, role
and data type are shown in Table 3.1.

As shown in Table 3.1, there were 7 determinants. A
ll determinants were binary
variables.
The outcome of interest in this study was CKD among
gout patients in Nongjik’s
Hospital, Pattani Province, which were of binary da
ta type.
3.2 Distribution of Determinants
Table 3.2 shows the frequency distribution of categ
orical determinants. There were
167 gout patients in Nongjik Hospital, Pattani Prov
ince. Overall, more than half
(62.9%) were overweight. Almost 90% of patients had
any of the considered co-
morbidities, HT (76.0%), dyslipidemia (49.7%) and D
M (17.4%) being the most
common.
Considering the use of thiazide, only 9.6% of patie
nts received thiazide to
treat high
blood pressure. Allopurinol plus colchicine were th
e most commonly dispensed (in
68.3% of patients with gout). There were 53 subject
s
(31.7%) who received
colchicine alone.
Approximately 45% of patients achieved the serum ur
ic acid goal of < 8 mg/dl.
