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
Dietary free fatty acids induce preadipocyte differentiation in the presence of a hormonal cocktail in 3T3-L1 adipocytes. Plant polyphenols are curb adipocyte differentiation and protect from metabolic stress. In the present study, we examined the effects of the saturated fatty acid, palmitic acid (PA) in presence of flavonoids, chrysin (CR) and hesperidin (HD) and phenolic acid, syringic acid (SYA) and sinapic acid (SIA). Adipocytes were incubated for 10 d with 100 μmol of PA along with 10-100 µmol CR/HD and 100-1000 µmol SYA/SIA. PA induced clonal expansion of preadipocytes, differentiation and oxidative stress in 3T3-L1 cells following 10 d of differentiation. Adipocytes treated with PA exhibited an increase of 300% in clonal population, 110% lipid and 172% reactive oxygen species accumulation. But treatment with CR, HD, SYA and SIA in the presence of PA concentration-dependent effect was observed. Concentrations of CR/HD and SYA/SIA inhibited PA-induced mRNA expression of PPARγ, C/EBPα, SREBP-1c, FAS and NOX4. Moreover, CR, HD, SYA and SIA did not exhibit toxicity in Drosophila DNA. In summary, these results suggest that dietary fatty acids act directly on adipocytes and addition of CR, HD, SYA and SIA resulted in reduction of PA-induced negative effects on 3T3-L1 adipocytes. HIGHLIGHTS: • Palmitic acid, the common dietary free fatty acid, is known to induce adipogenesis in 3T3-L1 adipocytes. • Treatment of differentiating adipocytes with flavonoids and phenolic acids reduced palmitic acid-induced clonal expansion of preadipocytes. • Phytocompounds reduced lipid accumulation and triglyceride production as well as ROS accumulation. • Thus, the phytocompounds showed effective anti-adipogenic activity even in palmitic acid challenged environment in adipocytes.
