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

Quaternary ammonium compounds (QACs) are frequently used chemicals in consumer, medical, and personal care products that could be detected in blood samples from the general population. Cord blood samples are frequently employed in epidemiological studies to evaluate the links between contaminant exposure and birth outcomes. However, a significant knowledge gap persists regarding the presence of QACs in cord blood and their potential associations with birth outcomes. In this study, QACs were analyzed in 235 cord blood samples collected in a hospital in Jinan, Shandong Province, from February 2017 to January 2022. QACs were detected in the investigated cord blood samples, with total concentrations reaching up to 47.3 ng/mL. Benzylalkyldimethyl ammonium compounds (BACs) accounted for the largest proportion, with BAC-C12 and BAC-C14 being the most abundant QACs. The multiple linear regression (MLR) and Bayesian kernel machine regression (BKMR) models were developed to explore the relationships between QACs exposure and newborn birth outcomes. Results showed that BAC-C10, BAC-C16, and octyl decyldimethyl ammonium-8:10 were positively associated with birth weight and ponderal index (
