Tumor growth reduction is regulated at the gene level in Walker 256 tumor-bearing rats supplemented with fish oil rich in EPA and DHA.

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
We investigated the effect of fish oil (FO) supplementation on tumor growth, cyclooxygenase 2 (COX-2), peroxisome proliferator-activated receptor gamma (PPARγ), and RelA gene and protein expression in Walker 256 tumor-bearing rats. Male Wistar rats (70 days old) were fed with regular chow (group W) or chow supplemented with 1 g/kg body weight FO daily (group WFO) until they reached 100 days of age. Both groups were then inoculated with a suspension of Walker 256 ascitic tumor cells (3 × 10(7) cells/mL). After 14 days the rats were killed, total RNA was isolated from the tumor tissue, and relative mRNA expression was measured using the 2(-ΔΔCT) method. FO significantly decreased tumor growth (W=13.18 ± 1.58 vs WFO=5.40 ± 0.88 g, P<0.05). FO supplementation also resulted in a significant decrease in COX-2 (W=100.1 ± 1.62 vs WFO=59.39 ± 5.53, P<0.001) and PPARγ (W=100.4 ± 1.04 vs WFO=88.22 ± 1.46, P<0.05) protein expression. Relative mRNA expression was W=1.06 ± 0.022 vs WFO=0.31 ± 0.04 (P<0.001) for COX-2, W=1.08 ± 0.02 vs WFO=0.52 ± 0.08 (P<0.001) for PPARγ, and W=1.04 ± 0.02 vs WFO=0.82 ± 0.04 (P<0.05) for RelA. FO reduced tumor growth by attenuating inflammatory gene expression associated with carcinogenesis.
