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
A novel matrix reference material (RM) for accurate determination of bisphenol A (BPA), bisphenol F (BPF), bisphenol S (BPS) and bisphenol AF (BPAF) in fish muscle was first developed. The RM candidate was prepared by intraperitoneal administration of target compounds to tilapia, followed by muscle mincing, homogenization, freeze-drying, milling and subpacking. Homogeneity, stability and characterization studies of the RM were carried out using an optimized isotope dilution-liquid chromatography tandem mass spectrometry (ID-LC-MS/MS) method. Sufficient homogeneity of the RM is suggested by ANOVA analysis. Short-term and long-term stability assessments, based on linear regression analysis, indicated no significant time-dependent drift for the RM stored at 60 °C for 10 days or at -20 °C for 12 months. From an interlaboratory study involving eight laboratories, the assigned indicative values of the RM were 8.71 μg/kg for BPA, 7.36 μg/kg for BPF, 10.10 μg/kg for BPS, and 5.43 μg/kg for BPAF, with corresponding expanded uncertainties (
