| Abstract |
Until now, no long-term studies relating serum albumin level to mortality rate in prevalent haemodialysis (HD) patients have been conducted. We aimed to examine the association between serum albumin level and mortality over a 5-year period. This study included 781 patients who received maintenance HD in a large, hospital-facilitated HD centre. Five-year medical records (2009-2013) were retrospectively reviewed, and the cut-off level for serum albumin level was set at 3.5 g/dL. The analysed albumin levels were expressed as time-averaged levels (first 24-month data) and albumin target reach rate over the first 2-year interval. Univariate and multivariate Cox proportional hazard regression models were used to examine the hazard function of the all-cause and cardiovascular mortality of the study participants in the subsequent 3-year period (2011-2013). Compared to those with a 100 % albumin reach rate (3.5 g/dL), the participants with 75- < 100, 50- < 75, and 1- < 50 % albumin reach rates exhibited significantly increased risk for all-cause mortality (HR 1.72, 95 % CI 1.19-2.47; HR 3.14, 95 % CI 1.91-5.16; HR 3.66, 95 % CI 2.18-6.16, respectively). A similar trend for all-cause mortality was demonstrated in participants with time-averaged albumin levels <4 g/dL (HR 1.57, 95 % CI 1.00-2.46 for 3.5-4.0 g/dL; HR 3.66, 95 % CI 2.11-6.32 for <3.5 g/dL). Compared to a 100 % albumin reach rate, the 50- < 75 and 1- < 50 % groups (HR 4.28, 95 % CI 1.82-10.01; HR 3.23, 95 % CI 1.22-8.54 respectively) showed significantly higher cardiovascular mortality rates. Similarly, participants with a time-averaged serum albumin level <3.5 g/dL exhibited a higher risk for cardiovascular mortality (HR 3.24, 95 % CI: 1.23-8.56). This long-term study demonstrated that higher reach rates of serum albumin levels and higher time-averaged serum albumin levels are associated with a lower mortality rate in patients undergoing maintenance HD. |

Attention Score in Context
This research output has an Altmetric Attention Score of 2. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 28 August 2016.
All research outputs
#14,931,785
of 23,881,329 outputs
Outputs from BMC Nephrology
#1,282
of 2,550 outputs
Outputs of similar age
#202,706
of 347,206 outputs
Outputs of similar age from BMC Nephrology
#32
of 58 outputs
Altmetric has tracked 23,881,329 research outputs across all sources so far. This one is in the 35th percentile – i.e., 35% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,550 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.0. This one is in the 46th percentile – i.e., 46% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 347,206 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 39th percentile – i.e., 39% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 58 others from the same source and published within six weeks on either side of this one. This one is in the 44th percentile – i.e., 44% of its contemporaries scored the same or lower than it.
