Involvement of primary afferent nerves after abdominal irradiation: consequences on ileal contractile activity and inflammatory mediator release in the rat.
Article in Digestive diseases and sciences, 2003. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
In this study we analyzed the role of substance P (SP) from afferent nerves in ileum contractibility and in the release of inflammatory mediators (neurotensin, Il-1beta, and TNF-alpha) in ileal mucosa and muscularis layers after a 10-Gy gamma-irradiation of the abdomen. Six hours after irradiation, SP concentrations were lower than in control rats, and 3 days after irradiation SP-induced contractile activity was higher. Irradiation significantly increased the levels of neurotensin, Il-1beta, and TNF-alpha in both layers. Pretreatment with capsaicin depleted afferent nerve endings of SP and reduced SP levels by about 50%. Capsaicin treatment reduced SP concentrations further, beyond the levels due to irradiation, thereby suggesting that all sources of SP are affected by irradiation. Capsaicin treatment prevented the irradiation from affecting SP-induced contractile response or increasing neurotensin levels. This finding suggests that SP released by afferent nerve endings controls these functions. Proinflammatory cytokine release was not reduced by capsaicin treatment.
