An environmentally relevant phthalate mixture impairs ovulatory prostaglandin and progesterone receptor pathways in human granulosa cells in vitro.
Article in Environment international, 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
Ovulatory defects are the leading cause of female infertility. Widespread exposure to endocrine-disrupting chemicals, such as phthalates, may contribute to the high prevalence of failed ovulation among infertile women. Using primary ovarian granulosa cells obtained from women, we tested the hypothesis that exposure to an environmentally relevant mixture of phthalate metabolites (MPTmix) impairs essential mediators of the ovulatory process, including progesterone (P4), progesterone receptor (PGR), and prostaglandins (PGs). The composition of the MPTmix was derived from urinary phthalate levels in women. Ovarian granulosa cells, obtained from in vitro fertilization patients, were acclimated in culture to regain responsiveness to hCG (human chorionic gonadotropin, clinical luteinizing hormone analogue). Following acclimation, cells were treated for 0.5-36hr with media containing DMSO (dimethyl sulfoxide, vehicle control), ± hCG (to initiate the ovulatory cascade), and ± MPTmix (1-500 µg/ml). Compared to hCG controls, treatment with hCG + MPTmix reduced active ovulatory PG levels by up to 77%, likely via decreased synthesis (lower PTGS2 and PTGES levels/activity), enhanced catabolism of PGE
