Urinary excretion of estrogenic chemicals following consumption of capsule coffee and French press coffee: A crossover study.
Article in Toxicology reports, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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: Coffee brewed from capsules contain estrogenic chemicals (ECs) that may harm the reproductive system. However, there are no studies investigating whether consuming capsule coffee causes these ECs to present in urine. Objective: Compare the effects of consuming capsule coffee vs. a plastic-free (French press) method on the appearance of ECs in urine. Methods: Participants (n = 30) were randomized to consume 540 mL of capsule or French press coffee once, then switched and consumed the other coffee after washout. Urine samples were collected prior to consumption, at 6 h and 24 h. Coffee and urine samples were analyzed for nine ECs using ultra-performance liquid chromatography with tandem mass spectrometry: bisphenol A (BPA), bisphenol F (BPF), bisphenol S, di(2-ethylhexyl) phthalate (DEHP), benzophenone, 4-nonylphenol (4-NP), dibutyl phthalate, caprolactam and dimethyl terephthalate. Results: In coffee samples, BPF (French press: 13.9 ng/mL, capsule: 16.1 ng/mL) and DEHP (capsule: 1.12 ng/mL) were present. In 6 h urine samples, the detection frequency for DEHP was 6.7% in capsule and 13.3% in French press coffee. BPF was detected in only one urine sample post-consumption. Conclusion: Consuming capsule coffee did not increase urinary EC exposure compared to consuming French press coffee.
