Inverse and Direct Effect of Serum DDE Exposure on the Distribution of Leukocyte Telomere Length in Brazilian Adults: The Pró-Saúde Study.

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: The current literature on associations between organochlorine pesticides and leukocyte telomere length (LTL) is conflicted, showing positive, inverse, or no association, findings that might be related to methodological issues and population characteristics, including the baseline LTL. Alternative exploration of this relationship over the whole LTL distribution may add information to help understand the role of pesticides in telomere shortening or enlargement. Objective: We evaluated the association between environmental dichlorodiphenyldichloroethylene (DDE) exposure and percentiles of LTL in a sample of adults living in the urban area of Rio de Janeiro, Brazil. Methods: LTL, serum pesticide concentration, and the covariates were determined cross-sectionally in a sample of 471 adults from the Pró-Saúde Study, a cohort of civil servants at a university campus in Rio de Janeiro, Brazil, conducted from July 2012 to October 2013. The percentiles (5th to 95th) of LTL (outcome variable) were modeled using quantile regression (QR) models with DDE as exposure and adjusted for age, sex, educational level, total body fat mass, total serum lipids, smoking, alcohol intake, and caloric share of Results: Discussion: DDE exposure predicts some quantiles of LTL distribution, with a positive relationship in the first quantiles and inverse at the highest quantile. This study added new information to help understand the role of pesticides in telomere shortening or enlargement; however, given the few studies and the conflicting results, longitudinal investigations are needed to clarify this association. https://doi.org/10.1289/JHP1033.
