Nanostructured Tin- and Titanium-Based Chemoresistive Sensors for Detecting Volatile Fingerprints from Colorectal Cancer Biopsies and Cell Lines.
Article in International journal of molecular sciences, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 represents a global health burden, being the third most frequently diagnosed cancer worldwide, accounting for about 1.9 million new cases annually, and the second leading cause of cancer-related deaths. This highlights the need for innovative and effective methods for cancer detection, improving current diagnostic approaches. In this feasibility study, two nanostructured chemoresistive gas sensors based on tin oxide-titanium oxide composites were selected to detect the metabolic patterns associated with human healthy and colorectal cancer tissues, collected from 26 patients. To further validate the biopsy-derived results, the sensors were tested on two colorectal cancer-derived cell lines, namely Caco-2 and RKO. Both sensors were able to discriminate between healthy and tumor samples by comparing the mean sensor responses, using the paired
