Time courses for clinical parameters in the azelnidipine group and the trichlormethiazide group.

The parameters are described as “mean ± SD” at 0, 24, and 48 weeks. The differences in parameters at 24 and 48 weeks relative to the baseline values (0 weeks) were analyzed using a paired t-test (*P < 0.05, **P < 0.01) or a Wilcoxon signed rank test (†P < 0.05, ††P < 0.01).

所有参数均以0、24和48周时的均值±标准差（mean ± SD）进行表述。以基线值（0周）为参照，针对24周及48周时的参数与基线值的差异，采用配对t检验（paired t-test，*P < 0.05，**P < 0.01）或Wilcoxon符号秩检验（Wilcoxon signed rank test，†P < 0.05，††P < 0.01）开展统计学分析。阿折地平组与三氯噻嗪组临床参数的时间变化曲线。
