Following publication of the original article [1], some numbers under the heading P4P & COCI in Table 2 needs to be moved from the column Model Aa to the column Model Bb. This problem is caused due to a typesetting error. The correct Table 2 is given below.

Table 2 Adjusted hazard ratios by Cox proportional hazard model for different risk factors of LEA

In calculating the cut-off points of tertiles for time-weighted average COCI 2010-2013, there was an error made in reporting so that the tertiles of the distribution of the COCI scores and thus the cutoffs should be corrected as follows:

  • “low COCI (< 0.360)” revised to (<0.50);

  • “middle COCI (0.360–0.643)” revised to (0.50-0.80);

  • “high COCI (≥ 0.643)” revised to (≥0.80).

Numbers to be revised are shown in the following 4 sections:

Page 1, Abstract, Results:

With the low COCI (<0.50) group as the reference, the aHR of LEA was 0.49 (p < 0.0001) for the middle COCI group, (p < 0.0001), and the aHR of LEA for the high COCI (≥0.80) group was 0.23 (p < 0.0001).

Page 3, Line 2:

We divided the COCI scores into 3 subgroups based on the tertiles of the distribution for analysis: low (<0.50), middle (0.50-0.80), and high (≥0.80).

Page 8, Left column, Line 9-12:

With the low COCI (<0.50) group as the reference, the aHR of LEA was 0.49 (p < 0.0001) for the middle COCI group, p < 0.0001, and the aHR of LEA for the high COCI (≥0.80) group was 0.23 (p < 0.0001).

Page 8, Right column, Line 4-8

In model B, with low COCI (<0.50) subgroup of non-P4P group as the reference, the aHR of LEA was 0.68 (p < 0.0001) for middle COCI subgroup of non-P4P group, 0.26 (p < 0.0001) for high COCI (≥0.80) …

The original article [1] has been corrected.
