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
backgroundNon-communicable diseases are chronic systemic inflammation in humans that occurs because of enhanced inflammatory mediators of the arachidonic acid cascade. We aimed to explore whether the lead chalcone compounds could exhibit anti-inflammatory activity via dual blockage of COX-2/5-LOX enzymes and their regulatory mechanism.
methodsRAW 264.7 macrophages were collected from NCC, Pune, for in-vitro experiments. The IC
resultsThe present study described the in-vitro and in-vivo biological evaluation of dual COX-2/5-LOX inhibitors in chalcone derivatives (C45 and C64) compounds showed the most effective COX-2 and 5-LOX inhibition with IC50 values 0.092 and 0.136 μM respectively. Simultaneously, compound C64 showed comparable selectivity towards COX-2 with a Selectivity Index (SI) of 68.43 compared to etoricoxib, with an SI of 89.32. In-vivo carrageenaninduced rat paw oedema activity, the compound C64 showed a significant reduction in oedema with 78.28% compared to indomethacin with 88.07% inhibition. Furthermore, cotton pelletinduced granuloma activity revealed that compound C64 significantly reduced 32.85% compared with standard 40.13% granuloma inhibition.
conclusionThe chalcone compound C64, (E)-1-(4-Amino-2-hydroxyphenyl)-3-(3,4,5-trimethoxyphenyl)- prop-2-en-1-one was proved to be a potent and novel Dual COX-2/5-LOX inhibitor with improved gastric safety profiling.
