Key findings
Hypertension ORs were 1.06 (PFOA), 1.12 (PFOS), and 1.08 (PFHxS). Sex interaction was significant; in men PFNA OR was 1.19. Absolute BP shifts were small.
Methodology
Authors used a community health-surveillance cohort after decades of PFAS in drinking water, measured serum PFAS, SBP/DBP, and hypertension, and ran confounder-adjusted models plus sex-stratified analyses.
Limitations
Cross-sectional data cannot prove PFAS caused hypertension, and the community is unusually highly exposed, so results may not match background-level populations.

Role on claims
Each row is a claim on a concept or method page where this paper supports, challenges, or qualifies the statement. Roles are hand-checked — not a model guess.
This library holds 10 empirical papers on persistent pollutants with measured outcomes rather than reviews.

Evidence for the claim as stated.
Indoor medians in one cohort are not global inventories, and detection is not a health effect.
Evidence for the claim as stated.
Veneto youth in a highly exposed drinking-water community had hypertension ORs of 1.06 (PFOA), 1.12 (PFOS) and 1.08 (PFHxS); in men the PFNA OR was 1.19. Absolute blood-pressure shifts were small. The ecological Veneto mortality paper reports a community median serum PFOA of 14 ng/mL — two orders of magnitude below Ronneby's PFOS/PFHxS medians and not an individual-dose analysis.
Evidence for the claim as stated.
PFAS biomonitoring is not one concentration or one health claim. Ronneby exposed medians are PFOS 157 ng/ml and PFHxS 136 ng/ml with 7–9% higher cholesterol; Veneto mortality work uses median PFOA 14 ng/mL as an ecological marker; Veneto youth BP ORs sit at 1.06–1.12 with small absolute shifts. Compound, concentration range and endpoint all differ.
