Hypertension and blood lead levels among battery technicians and office workers in western Nigeria.
Article in Journal of public health in Africa, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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: Occupational exposure to lead remains a significant public health concern because of its association with hypertension and cardiovascular disease. Battery technicians are particularly at risk because of prolonged exposure to lead-containing materials. Aim: This study assessed and compared blood lead levels (BLL), blood pressure (BP) profiles and associated risk factors among battery technicians and office workers in Western Nigeria. Setting: The study was conducted in Lagos State, Nigeria. Methods: A cross-sectional study design was employed using multistage sampling. Data were collected with a structured interviewer-administered questionnaire, and BP measurements were obtained. Data analysis was performed using the Statistical Package for Social Sciences version 20. Chi-square, Mann-Whitney U, Fisher's exact and Student's Results: Median systolic blood pressure (SBP) was statistically significantly higher among battery technicians (124 mmHg) compared to office workers (119.33 mmHg) ( Conclusion: Battery technicians exhibited higher SBP levels than office workers. Improved workplace safety practices, regular use of protective devices, personal hygiene and routine biological monitoring may reduce elevated lead and hypertension among battery technicians in Nigeria. Contribution: Improved workplace safety and practices, regular use of PPEs and personal hygiene, and routine biological monitoring among battery technicians in Nigeria may reduce elevated lead and hypertension among battery technicians.
