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
Objective: Oxidative stress develops because of a shift in the prooxidant-antioxidant balance toward the former, because of disturbances in redox signaling and control. Celecoxib (Cb), a selective COX-2 inhibitor, is a drug that effectively decreases pain and inflammation. However, Cb causes oxidative injury to hepatic tissues via enhanced lipid peroxidation, thus resulting in excessive production of reactive oxygen species. Consequently, frequent or long-term Cb use may lead to hepatic, renal, and other noticeable adverse effects. Lycopene (lyco), a potent antioxidant naturally occurring in pigmented fruits and vegetables, actively eradicates singlet oxygen and other free radicals, thereby protecting cells against destruction of the plasma membrane by free radicals. Methods: We hypothesized that lyco might protect rat liver cells against Cb-induced oxidative stress, thus reducing fatty infiltration and glycogen depletion. Rats were randomized into three groups (with ten rats each) receiving control (group A, saline only), Cb (group B, 50 mg/kg, orally), or Cb + lyco (group C, 50 mg/kg, orally) for 30 days. Subsequently, liver tissues were examined, and the average liver weight and histological changes in fat and glycogen content were determined. Results: Lyco mitigated hepatocyte damage in Cb-treated rats, reducing fat accumulation and glycogen loss, probably through its antioxidant properties. Concomitant lyco and Cb intake prevented hepatotoxic adverse effects due to oxidative injury, as well as non-alcoholic fatty liver disease (NAFLD), a key component of metabolic syndrome. Moreover, the binding orientation of lyco in the binding site of COX-2 enzyme revealed that the docked complex had noteworthy binding strength. Conclusion: In conclusion, our study revealed lyco's protective effects against Cb-induced hepatic damage by reducing fat and glycogen depletion.
