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
Bisphenol A （BPA） and its analogs are collectively termed bisphenol compounds （BPs）， which are predominantly utilized in the manufacturing of polycarbonate plastics and epoxy resins. BPs are ubiquitous in diverse environmental matrices， human tissues， and metabolic products. Extensive research has demonstrated that BPs exert adverse effects on the nervous， reproductive， immune， and metabolic systems. After exposure in humans， BPs are primarily excreted in urine. Consequently， the development of efficient and robust analytical methods for BPs quantification in urine is essential for assessing population exposure levels. In this study， solid supported liquid-liquid extraction （SLE） was combined with ultra-high performance liquid chromatography-tandem mass spectrometry （UHPLC-MS/MS） technology to establish a high-throughput determination method for 17 BPs in human urine. After enzymatic hydrolysis treatment of the samples， the steps of fully automatic SLE purification， nitrogen blowing concentration and redissolution were carried out successively. Separation was performed using a CAPCELL PAK ADME chromatography column （100 mm×2.1 mm， 2 μm）， and gradient elution was carried out with 0.05 mmol/L ammonium fluoride aqueous solution and 0.05 mmol/L ammonium fluoride methanol solution as the mobile phases. MS detection was carried out using the electrospray ionization （ESI） negative ion scanning mode under the multi-reaction monitoring （MRM） mode. Qualitative analysis was conducted based on retention time and ion abundance ratio， and quantitative analysis was performed using the internal standard method. Under the optimized conditions， 17 BPs can be effectively separated. The linear relationships of the 17 BPs within the corresponding mass concentration ranges were good， and the correlation coefficients （
