Association of serum intestinal fatty-acid binding protein, inflammatory and oxidative stress markers with colorectal cancer among Ghanaian patients.
Article in PloS one, 2025. 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
backgroundIn sub-Saharan Africa, colorectal cancer (CRC) is becoming an increasingly serious public health issue. However, little is known about the relationships between inflammation, oxidative stress, and intestinal barrier biomarkers in African populations. This study examined the association between selected biomarkers, dietary factors, and the risk of CRC among treatment-naïve patients in Ghana.
methodsThis hospital-based analytical cross-sectional study included twenty-eight CRC patients and twenty-six non-CRC volunteers. Serum samples processed from whole blood were analyzed for tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and intestinal fatty acid binding protein (iFABP) levels using enzyme-linked immunosorbent assays (ELISA). The thiobarbituric acid test was used to measure the concentration of serum malondialdehyde (MDA). Dietary intake data were collected using structured questionnaires. Logistic regression models were used to evaluate associations with CRC risk.
resultsCRC patients showed significantly higher levels of TNF-α, IL-1β, MDA and iFABP compared to the control group (p < 0.05). A Pearson correlation analysis revealed a significant positive correlation between IL-1β and TNF-α levels (r = 0.606, p < 0.000). TNF-α and MDA levels were significantly associated with increased odds of CRC in both crude and adjusted models (p < 0.05). In contrast, IL-1β and iFABP showed only crude significant associations with CRC. Dietary factors, including alcohol consumption, red/processed meat, vegetables, and dairy intake, were not significantly associated with CRC risk.
conclusionThe study identifies TNF-α and MDA as potential biomarkers associated with CRC, emphasizing the role of inflammation and oxidative stress in CRC pathogenesis in Ghana. The lack of adjusted association with iFABP may reflect population-specific patterns or limited statistical power. Further large-scale longitudinal studies are warranted.
