Table 2. Do thiazides diuretics have a significant effect on blood pressure variability?

Review 1	Thiazide group	Placebo group
SD of SBP±SE mmHg
Baseline	14.9±0.99 (n = 14)∧	14.1±0.75 (n = 14)∧
End of treatment ∧∧	14.3±0.71 (n = 14)	14.0±0.82 (n = 14)
CV of SBP±SE %
Baseline	9.5±0.57 (n = 14)∧	9.0±0.39 (n = 14)∧
End of treatment ∧∧	9.9±0.42 (n = 14)	9.4±0.53 (n = 14)
SD of DBP±SE * mmHg
End of treatment ∧∧	7.6±0.37 (n = 23)	6.9±0.39 (n = 23)
CV of DBP±SE * %
End of treatment ∧∧	8.2±0.39 (n = 23)	7.2±0.43 (n = 23)

SD = Standard Deviation; SE = Standard Error; SBP = Systolic Blood Pressure; DBP = Diastolic Blood Pressure; CV = Coefficient of Variation; n = number of observations.

^∧Paired t test between baseline versus end of treatment is not significant for SD of SBP as well as CV of SBP in both thiazide and placebo groups.

^*Only end of treatment values for SD as well as CV of DBP were analyzed since baseline values are confounded.

^∧∧Unpaired t test at end of treatment between thiazide versus placebo groups is not significant for SD as well as CV of both SBP and DBP.
