1 · What the graph read from it

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.

2 · The registry

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

objectiveTo investigate the effects of lycopene supplementation on inflammation, lung histopathology and systemic DNA damage in an experimentally induced lung injury model, ventilated by conventional mechanical ventilation and high-frequency oscillatory ventilation, compared with a control group.

methodsFifty-five rabbits sampled by convenience were supplemented with 10mg/kg lycopene for 21 days prior to the experiment. Lung injury was induced by tracheal infusion of warm saline. The rabbits were randomly assigned to the control group and subjected to protective conventional mechanical ventilation (n = 5) without supplementation or the experimental group that was subjected to acute lung injury and provided conventional mechanical ventilation and high-frequency oscillatory ventilation with and without lycopene supplementation (n = 10 rabbits in each group). Lung oxidative stress and the inflammatory response were assessed based on the number of polymorphonuclear leukocytes in bronchoalveolar lavage fluid, DNA damage and pulmonary histological damage.

resultsA significant worsening of oxygenation and a decrease in static lung compliance was noted in all groups after pulmonary injury induction (partial pressure of oxygen before 451.86 ± 68.54 and after 71 ± 19.27, p < 0.05). After 4 hours, the high-frequency oscillatory ventilation groups with and without lycopene supplementation as well as the group receiving protective conventional mechanical ventilation with lycopene supplementation showed significant oxygenation improvement compared with the protective conventional mechanical ventilation group without supplementation (partial pressure of oxygen of the group with mechanical ventilation without lycopene of 102 ± 42, of the group that received conventional protective mechanical ventilation with lycopene supplementation of 362 ± 38, of the high-frequency group without lycopene supplementation of 420 ± 28 and of the high-frequency group with lycopene supplementation of 422 ± 25; p < 0.05). Compared with rabbits not receiving supplementation, those in the groups that received protective conventional mechanical ventilation with lycopene supplementation and high-frequency oscillatory ventilation with lycopene supplementation had significantly less inflammation as well as less histological injury (p < 0.05). Compared with rabbits subjected to protective conventional mechanical ventilation, significantly lower DNA damage was observed in rabbits supplemented with lycopene (p < 0.05).

conclusionLycopene supplementation reduces inflammatory and histopathological lung injuries, regardless of the associated ventilatory mode. In addition, lycopene improved oxygenation and reduced DNA damage when protective conventional mechanical ventilation was used.
