Esophageal COX-2 expression is increased in Barrett's esophagus, obesity, and smoking.
Article in Digestive diseases and sciences, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
backgroundIncreased esophageal cyclooxygenase-2 (COX-2) expression has been associated with Barrett's esophagus (BE); however, it is unknown whether COX-2 expression varies among patient groups with different clinical or socio-demographic factors.
methodsWe conducted a case-control study among eligible patients scheduled for elective esophagogastroduodenoscopy and patients eligible for screening colonoscopy recruited from primary clinics. We compared 39 BE tissue samples and 47 squamous tissue samples from BE cases and 240 squamous tissue samples from controls. Clinical and socio-demographic data were prospectively collected. Immunohistochemical staining for esophageal COX-2 was performed and scored.
resultsThe median COX-2 score was significantly higher in BE tissue than squamous tissue from cases or controls (p < 0.001). Median COX-2 expression levels were higher in tissue samples from participants with a waist-to-hip ratio (WHR) in the 2nd tertile [unadjusted odds ratio (OR) 2.04; 95 % confidence interval (95 % CI) 1.17-3.57] and 3rd tertile (unadjusted OR 2.24; 95 % CI 1.20-4.16) compared with the 1st tertile and from current smokers compared with former or non-smokers (unadjusted OR 1.68; 95 % CI 1.03-2.75). In the multivariate analysis, WHRs in the 2nd tertile (OR 1.92; 95 % CI 1.07-3.45) and the 3rd tertile (OR 2.14; 95 % CI 1.10-4.16) were associated with high COX-2 compared with the 1st tertile, as was current smoking (OR 1.78; 95 % CI 1.06-2.97) compared with former and non-smoking.
conclusionWe found a significant association between elevated esophageal mucosa COX-2 levels and the presence of BE tissue, as well as between elevated COX-2 levels and high WHR and current tobacco smoking. This information may assist in identifying patients likely to benefit from chemoprevention with COX-2 inhibitors.
