Colorectal Cancer Label-Free Impedimetric Immunosensor for Blood-Based Biomarker CCSP-2.

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
Colorectal cancer (CRC) is one of the most treatable cancers, yet it ranks second in mortality worldwide. Early detection significantly impacts treatment outcomes, but early stage CRC often presents no symptoms or nonspecific symptoms. The current screening methods are invasive and lacks specificity, hindering widespread CRC screening efforts. This underscores the urgent need for improved CRC screening tools. In this study, a label-free impedimetric immunosensor for detecting colon cancer-secreted protein-2 (CCSP-2), which exhibits a mean 78-fold increase in primary colon cancers compared to normal mucosa, was developed. Our cost-effective and noninvasive electrochemical immunosensor for CCSP-2 biomarker detection aims to facilitate early diagnosis and monitoring of CRC. The designed immunosensor features a functionalized gold electrode (Au) modified with cysteine-modified recombinant protein G (RPGCys) to immobilize the CCSP-2 antibody (Ab), and bovine serum albumin (BSA) used to prevent sensor surface fouling. Electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV) were employed to analyze the electrochemical response to the binding of CCSP-2 antigen (Ag) and Ab. The changes in relative charge transfer resistance (Δ
