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
Background and study aims: Magnifying endoscopy with narrow-band imaging (ME-NBI) is regularly used in neoplasia diagnostics although its use in assessment of esophageal inflammatory changes is uncommon. The aim of this study was to evaluate the efficacy of eosinophilic esophagitis reference score and ME-NBI signs in predicting inflammation using gastroscopy with dual focus in patients with dysphagia. Patients and methods: We conducted a prospective cohort study in adults undergoing gastroscopy with esophageal biopsies because of dysphagia/food bolus impaction. Number of eosinophiles and lymphocytes were calculated per high-power field. We used logistic regression with forward stepwise selection to determine the most relevant predictors (endoscopic signs) of inflammation. To assess the predictive value of endoscopic signs for eosinophilic or lymphocytic infiltration, we calculated sensitivity, specificity, and predictive values. Results: In total 219 patients (71.2% male) were enrolled to the study. Most frequent endoscopic findings were furrows (121/219, 55%), positive NBI signs (106/219, 48%), and edema (102/219, 47%). Logistic regression analysis showed that furrows and NBI signs were the most significant predictors of eosinophilic infiltration. Edema was the only significant predictor of lymphocyte infiltration. Conclusions: Positive NBI signs and furrows were the best predictors of eosinophile infiltration, whereas lymphocytic infiltration was predicted by edema. Given that NBI is already widely available, we encourage use of both white light and NBI in patients with suspected esophageal inflammation.
