1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Background This study aims to explore whether higher blood lead levels (BLL) may be associated with failure to control blood pressure and subsequent uncontrolled hypertension. Methods and Results We used serial cross-sectional waves of the US National Health and Nutrition Examination Survey (NHANES) from 1999 to 2016. 30 762 subjects aged 20 years and above were included. Uncontrolled hypertension was defined as systolic blood pressure ≥130 mm Hg or diastolic blood pressure ≥80 mm Hg. We estimated odds ratios (ORs) of quartiles of BLL for any hypertension and uncontrolled hypertension by sex using logistic regression, adjusted for demographics, smoking status, serum cotinine, alcohol intake, body mass index, and menopause status in women. The weighted prevalence of hypertension was 46.7%, of which 80.1% were uncontrolled. Men, younger ages, ethnic minorities, people with lower income, never and current smokers, and people with higher BLL were less likely to have their hypertension controlled. In men, compared with the lowest quartile of BLL (<0.94 μg/dL), the highest 2 quartiles (0.94-1.50 μg/dL, 1.50-2.30 μg/dL) were associated with hypertension (Q2: OR, 1.12; 95% CI, 0.96-1.30; Q3: OR, 1.16; 95% CI, 1.01-1.34; Q4: OR, 1.25; 95% CI, 1.08-1.45), but not in women. In hypertensive men, higher BLL was related to uncontrolled hypertension compared with the lowest quartile (Q2: OR, 1.34; 95% CI, 0.98-1.85; Q3: OR, 1.70; 95% CI, 1.26-2.30; Q4: OR, 1.96; 95% CI, 1.45-2.65). In women, the relationship was similar (Q2: OR, 1.26; 95% CI, 0.95-1.67; Q3: OR, 1.48; 95% CI, 1.10-2.00; Q4: 1.70; 95% CI, 1.26-2.30). Conclusions BLL is associated with higher prevalence of hypertension and uncontrolled hypertension, with more pronounced association in men.
