3). Reducing kidney function was defined as 25th eGFR percentile or lower. Figure 3a shows the ROC curve for office SBP, Fig. 3b for 24-h mean BP, and Fig. 3c for HBI. Areas under the curves were 0.58, 0.61, and 0.61 for each. p value between office SBP and 24-h mean SBP was 0.16, and that between office SBP and HBI was 0.23. Fig. 3 ROC curve analysis to

discriminate low renal function ROC curves for office SBP (a), 24-h SBP (b), HBI (c) and all of them (d). Decreased renal function was defined as 25th eGFR percentile or lower. AUCs of office SBP were 0.58/0.59/0.58 (all/female/male), those of 24-h SBP were 0.61/0.62/0.61 (same as above) and those of systolic HBI were 0.61/0.61/0.61 (same as above). Since there are not apparent differences among ROC curves of all subjects, females and males, only ROC curves of all subjects were shown. selleck screening library Nonparametric approach to ARRY-438162 compare these three ROC curves was performed and office SBP was used as the reference. p value between office SBP and 24-h mean SBP was 0.16/0.40/0.27 (all/females/males), and that between office SBP

and HBI was 0.23/0.71/0.25 (same as above). (- — – office SBP; – - – - 24-h mean SBP; —— systolic HBI) The relationship between HBI, NBPC, and eGFR Finally, we examined the relationship between two ABPM indicators (HBI selleckchem and NBPC) and eGFR at the same time point. First, patients were divided into two groups by NBPC: one is sufficient NBPC group with dipper or extreme-dipper, and the other is insufficient NBPC group with non-dipper or riser. And then each group is divided into two groups by with/without BP load (Fig. 4). eGFR was lower in subjects with high BP load than with low BP load, even if they had sufficient NBPC. The same tendency was observed with males and females, that is, the median eGFR is lower with BP load (+) than BP load (−) both in the group of sufficient NBPC (NBPC is 10 % or over) and in the group of insufficient NBPC,

and median eGFR was the lowest in the group categorized Celecoxib with insufficient NBPC and with high BP load. Fig. 4 Box-and-whisker plots on eGFR for males and females. Subjects were divided into four groups by NBPC (<10 % or ≥10 %) and with/without BP load, and the box-and-whisker plots on eGFR were made to clarify the difference among them. The length of the box represents the interquartile range (the distance between the 25th and the 75th percentiles). The dot in the box interior represents the mean. The horizontal line in the box interior represented the median. The vertical lines issuing from the box extended to the minimum and maximum values of the analysis variable.
