The Influence of Persistent Organic Pollutants on Thyroidal, Reproductive and Adrenal Hormones After Bariatric Surgery.
Article in Obesity surgery, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 3 of them syntheses that pooled 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.
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
introductionPersistent organic pollutants (POPs) including organochlorine pesticides, polychlorinated biphenyls (PCBs), and per- and polyfluoroalkylated substances (PFASs) are suspected endocrine disruptors.
aimTo evaluate the associations between POPs and thyroidal, reproductive, and adrenal hormones in a study population treated with bariatric surgery.
methodsBlood samples from a cohort of 63 participants before and 1 year after bariatric surgery were analyzed for 16 lipophilic POPs, 17 PFASs, and thyroidal, reproductive, and adrenal hormones. Participants reporting relevant medical conditions or interfering medication were excluded, and plausible confounders were corrected for in multiple regression analyses.
resultsFree thyroxine (fT
conclusionThe results suggest that POPs may have an influence on the hypothalamic-pituitary-thyroid (HPT) and the hypothalamic-pituitary-gonadal (HPG) axes after bariatric surgery. Because of small sample sizes and discrepancy in the sampling time points pre- and postoperatively, the observed hormonal impacts of POPs must be interpreted as associative and not causative. Further studies are needed to confirm the findings.
