Effect of ibuprofen on cyclooxygenase and nitric oxide synthase of gastric mucosa: correlation with endoscopic lesions and adverse reactions.
Trial report in Digestive diseases and sciences, 2004. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
The aim of this study was to evaluate the effect of ibuprofen on gastric mucosa and enzymes involved in gastroprotection in healthy volunteers. Twenty-four Helicobacter pylori-negative subjects were randomized to treatment with ibuprofen or ibuprofen-arginate (each 600 mg/6 hr during 3 days). Endoscopies were performed 1 week before and after treatment. Biopsies were taken from the gastric antrum and corpus for determination of prostaglandin E2 (PGE2) by ELISA and cyclooxygenase (COX-1 and COX-2) and nitric oxide synthase (eNOS and iNOS) by western blot. All subjects had at least one gastric lesion except for two individuals taking ibuprofen-arginate. Ibuprofen-arginate caused a lower rate of clinical adverse reactions than ibuprofen. Subjects with gastric lesions or adverse reactions had lower PGE2 levels. COX-1, COX-2, eNOS, and iNOS were detectable in all subjects. The constitutive enzymes (COX-1 and eNOS) did not change after treatment. COX-2 was higher in corpus than antrum and it increased after ibuprofen treatment. iNOS tended to increase mildly in the corpus in subjects with adverse reactions or endoscopic lesions. There were no significant differences between ibuprofen and ibuprofen-arginate in PGE2, or enzymes.
