In Volume 32, Issue 6 (2018), Table 1 was incorrect in the article titled “Concordance between point‐of‐care blood gas analysis and laboratory autoanalyzer in measurement of hemoglobin and electrolytes in critically ill patients” by Shivesh Prakash, Shailesh Bihari, Zhan Y. Lim, Santosh Verghese, Hemant Kulkarni, and Andrew D. Bersten.
In Table 1 the column headings, “BGA” and “AA” under “Mean (SD)” should be swapped to say “AA” and “BGA,” respectively.
The updated table is as follows:
| Analyte | N | Mean (SD) | Concordance correlation coefficient | Limits of agreement | Bias | No. of pairs outside US CLIA limits | ||
|---|---|---|---|---|---|---|---|---|
| AA | BGA | Point | 95% CI | |||||
| Hemoglobin (g/L) | 9198 | 98.29 (18.99) | 100.28 (19.57) | 0.98 | 0.984‐0.985 | −7.471‐3.486 | −2.19 | 554 (5.9%) |
