Integrating chronic inflammation and hypoxia: the potential role of HIF-1α in tumor behavior and therapy response in high-grade serous ovarian cancer.

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
High-grade serous ovarian carcinoma (HGSOC) is marked by late diagnosis and chemoresistance, partly driven by chronic inflammation and hypoxia in the tumor microenvironment. Hypoxia-inducible factor 1-alpha (HIF-1α) is a key regulator of these processes; however, its spatial distribution, interaction with inflammation, and effect on chemotherapy response in HGSOC remain unclear. This retrospective study included 28 advanced HGSOC patients treated with neoadjuvant chemotherapy (NACT). Samples were collected at primary surgery (PS) (ovarian and peritoneal tissue, plasma, ascites) and post-NACT at interval debulking surgery (IDS) (omentum, peritoneal tissue, plasma). HIF-1α mRNA expression varied by site, with higher levels in omental and peritoneal tissues compared to ovarian tissue. Plasma and ascites concentrations were significantly correlated, although the mean ascites concentration was lower. Elevated HIF-1α concentration in ascites and plasma at baseline correlated with ESR (erythrocyte sedimentation rate) >30 mm/h, which was also correlated with
