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
Disruptions in lipid metabolism can hasten disease progression and impose a heavier burden on patients with nasopharyngeal carcinoma (NPC). We previously observed a positive correlation between zinc finger and BTB domain-containing protein 7A (ZBTB7A) and the long non-coding RNA antisense non-coding RNA in the INK4 locus (ANRIL), indicating a potential link between NPC and lipid metabolism; however, the underlying mechanism remains unclear. This study investigated primary NPC tissues that had significantly lower ZBTB7A expression than that in normal nasopharyngeal epithelium. Subsequent results confirmed that ANRIL promoted ZBTB7A expression by sponging miR-339-5p. ZBTB7A directly promoted ANRIL expression but inhibited SREBP1 and FASN expression. Thus, the ANRIL/miR-339-5p/ZBTB7A axis creates a positive feedback loop that suppresses the lipid pathway. Combining stable ANRIL overexpression with ZBTB7A shRNA effectively reduced lipid metabolism and the migratory, invasive, and metastatic capacities of NPC cells in vitro and in vivo. Furthermore, the SREBP inhibitor, fatostatin, enhanced the suppression of NPC metastasis. Our results indicated that interventions targeting ANRIL-shZBTB7A and SREBP inhibitors can effectively disrupt lipid metabolism and impair the invasive and metastatic properties of NPC cells. These findings provide valuable insights into the potential experimental strategies for inhibiting NPC metastasis.
