Abstract

The authors regret. 1. Abstract: “Compared with linear PFOS (n-PFOS), branched PFOS isomers (Br-PFOS) were more strongly associated with eGFR (Br-PFOS; β = −1.22, 95%CI: 2.02, −0.42; p = 0.003 vs. n-PFOS; β = −0.16, 95%CI: 0.98, 0.65; p = 0.691) and CKD (Br-PFOS; OR = 1.27; 95% CI: 1.02, 1.58; p = 0.037 vs. n-PFOS; OR = 0.98; 95% CI: 0.80, 1.20; p = 0.834).”The data “2.02” “0.98” should be “−2.02” “−0.98” respectively. 2. Results, paragraph 2: “For example, a ln-unit higher of n-PFOS was associated with a mean lower eGFR of −0.16 mL/min/1.73m2 (95% CI: 0.98, 0.65; p = 0.691) and a ln-unit higher of Br-PFOS was associated with a mean lower eGFR of −1.22 mL/min/1.73m2 (95% CI: 2.02, −0.42; p = 0.003).”The data “2.02” “0.98” should be “−2.02” “−0.98” respectively. 3. Results, paragraph 4: “… except for an attenuated and non-significant effect estimate for PFOA association (β = 0.54; 95% CI: 0.52, 1.61; p = 0.316), …”The data “0.52” should be “−0.52”. 4. Discussion, paragraph 2: “They found higher serum PFOA and PFOS levels were negatively associated with eGFR levels (Q4 v. Q1: PFOA (β = −5.7, 95%CI: 7.9, −3.5; p for trend <0.0001), PFOS (β = −6.7, 95%CI: 8.9, −4.4; p for trend <0.0001)), …”The data “7.9” “8.9” should be “−7.9” “−8.9” respectively. 5. Discussion, paragraph 2: “ … and with no associations for PFNA and PFHxS (Q4 v. Q1: PFOA (β = −6.84 mL/min/1.73m2; 95%CI: 11.48, −2.19), PFOS (β = −9.69 mL/min/1.73m2; 95% CI: 14.78, −4.59).”The data “11.48” “14.78” should be “−11.48” “−14.78” respectively. 6. Discussion, paragraph 5: “In another recent birth cohort study in Guangzhou, China (n = 321), Li et al. (2017) reported stronger negative effects for branched PFOS isomers (β = −126.3 g; 95%CI: 195.9, −56.8) than linear PFOS (β = −57.2 g; 95%CI: 103.1, −11.3) on birth weight.”The data “195.9” “103.1” should be “−195.9” “−103.1” respectively.
