Following publication of the original article [1], the authors reported an error in Fig. 3 and Additional file 1: Figure S3. This arose due to a coding error during the original analysis. The information in these two figures is supplanted by that provided in Table 4 and Additional file 1: Table S10, below. The correction of this error necessitates three changes to the text of the manuscript.
First, in the abstract, it was stated that: “Patient perceptions of general health were not correlated (R<0.05) with PCS or SPKD.” We correct this statement to “Patient perceptions of general health were correlated with PCS and SPKD (R = 0.487 and 0.352, respectively).”
Second, in the results section, it was stated that: “However, patients’ responses to item 1 on the KDQOL-36™ (“In general, would you say your health is:” a component of PCS) did not correlate with either PCS or SPKD (R < 0.05).” We correct this statement to “Patients’ responses to item 1 on the KDQOL-36TM were correlated with both PCS and SPKD (R = 0.487 and 0.352, respectively).”
Third, in the discussion section, it was stated that: “Strikingly, the response to item 1 on the KDQOL-36™ (“In general, would you say your health is”) was not correlated with any of the 5 subscale scores, nor with the response to any individual item on SPKD. This is notable in that patient-reported general health is thought to reflect aspects of health that are difficult to capture via clinical measures, and is independently associated with mortality risk [24]. This finding suggests that efforts to identify factors that influence perceptions of general health among dialysis patients, and the inclusion of such factors on survey instruments, may facilitate more nuanced understanding of HRQOL.” Because these statements are not supported by the corrected analysis, this paragraph should be removed.
