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
Objectives: To date, predictive and prognostic biomarkers for Bladder Cancer (BC) remain lacking. Existing literature underscores the potential of metabolomics as a valuable tool for biomarker identification. The primary objective of this study is to characterize the serum metabolic profile of BC patients undergoing platinum-based chemotherapy (Pt-CT) to identify potential biomarkers. Methods: In this pilot study, we investigated the metabolomic profiles of 14 BC patients undergoing Pt-CT in different settings. We compared their baseline profiles with those of healthy controls and tracked key metabolites throughout chemotherapy cycles. Metabolomics profiling was conducted using nuclear magnetic resonance (NMR) spectroscopy. All experiments were performed on a Bruker Avance™ 600 spectrometer. Results: Serum samples of BC patients had elevated levels of acetate, acetone, hypoxanthine, trimethylamine N-oxide (TMAO), glutamate, lactate, phenylalanine, and ornithine. Conversely, there were decreased levels of carnitine, choline, betaine, aspartate, threonine, 2-hydroxybutyrate, 2-aminobutyrate and histidine when compared with healthy controls. Throughout the CT course, hypoxanthine, glutamate, and aspartate levels increased, while acetone, acetate and TMAO levels decreased. Conclusions: The results of our study confirm perturbations in several metabolic pathways in the serum samples of BC patients, including glycolysis, fatty acid, purine, and amino acid metabolism. Additionally, TMAO may contribute to BC development by fostering a pro-inflammatory and oxidative stress state. Furthermore, monitoring these metabolites could serve as a valuable tool for predicting treatment response. To the best of our knowledge, no metabolomic studies have assessed BC patients undergoing CT with longitudinal monitoring to identify changes in the metabolic profile induced by treatment.
