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

Relationships of lead exposure with blood pressure and blood lead with inflammation have been previously established yet, but the conclusions are still controversial. The objective of our study was to investigate the role of systemic inflammation in the relationships between blood lead concentration and blood pressure. We quantified the levels of blood lead and white blood cell count in 505 lead-exposed workers with 842 observations. Associations between blood lead, white blood cell count, and blood pressure were evaluated by using linear mixed models. We further performed mediation analysis to investigate the role of white blood cell count in the associations between blood lead concentration and blood pressure. We observed that each 1% increase of blood lead levels was significantly positively associated with a 0.9%, 1.7%, and 1.1% increases in systolic blood pressure, white blood cell count, and blood platelet count, respectively. Also, we found that the levels of white blood cell count were positively correlated with diastolic blood pressure and systolic blood pressure in a dose-response manner. Mediation analysis showed that the levels of white blood cell significantly mediated the associations between concentration of blood lead and systolic blood pressure. Collectively, our findings suggest that blood lead was positively associated with systolic blood pressure and that systemic inflammation might play a key role in this association.
