Connecting the changing trace elements spectrum and survival in sarcoma: a pilot study.

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
objectivesWhile some metals have been reported as carcinogens or potential carcinogens, only few modern-standard datasets including a large number of elements are available. The present analysis established a first trace elements spectrum by relating the concentration of metals and trace elements in the serum of sarcoma patients with survival data.
methodsPatients with sarcoma and controls were retrospectively selected from the International Sarcoma Kindred Study database (ISKS). As part of the ISKS study, blood samples were prospectively collected at the Leon Bérard Cancer Center from February 2012 to July 2019. Stable specimens and copper isotopes (
resultsIn total, 151 patients and 59 healthy controls were included. At the time of blood sample collection, 62% of patients had locally advanced or metastatic disease. Copper (Cu), copper/zinc (Cu/Zn) and potassium/rubidium (K/Rb) ratio were significantly higher in patients compared to controls and were also significantly higher in patients with advanced compared to early-stage sarcoma. Whereas S and Se were significantly correlated in patients, no correlation was observed in controls. Importantly, levels of K, Rb, Se, Fe, P, Si, S, δ
conclusionsThese results depict the metallomic spectrum in sarcoma and highlight substantial variation associated with survival, enhancing our understanding of sarcoma's biology.
