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
purposeEndocrine disruptors (EDs) interfere with the endocrine system leading to health consquences and reproductive derangements. Most EDs are environmental pollutants whose risk evaluation is hampered by the simultaneous exposure to a number of chemicals. Here we investigated the possible mechanistic involvement of Sertoli cells, the nurse cell population in the seminiferous tubule, in the reproductive toxicity of Bisphenol A (BPA) and perfluoro-octane sulphonate (PFOS), two acknowledged EDs, at recognized subacute toxic levels.
methodsMouse Sertoli cell line TM4 were exposed for 24 h to 40 ng/mL BPA or 30 ng/mL PFOS or their association. Cell proliferation was measuerd by MTT assay. Cell apoptosis was evaluated with Annexin-V/propidium iodide staining. Protein expression analysis was peformed by western blotting.
resultsCompared to unexposed controls (100.0 ± 3.5%), cells exposed to BPA (79.5 ± 3.5%) or PFOS (76.0 ± 7.9%) showed reduced survival rate (P < 0.001 vs control). The exposure to the mixture of BPA and PFOS was associated with a further reduction of cell survival (63.9 ± 7.2%, P < 0.001 vs control) and an increase of the percentage of apoptotic cells (13.7 ± 4.6% control, 40.3 ± 13.5% BPA, PFOS 28.7 ± 5.6%, 67.1 ± 19.6% BPA + PFOS P = 0.001 vs control; P = 0.022 vs BPA). The exposure to the combination of BPA and PFOS was associated with Akt-signaling pathway activation and with the downstream caspase 3 cleavage. In addition, the exposure to the combination of BPA and PFOS was associated with NF-κB activation and increased expression of FasL.
conclusionSubacute toxic levels of BPA and PFOS display additive effects on Sertoli cell apoptosis with the possible involvement of FasL-dependent germ cell apoptosis.
