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

objectivesNumerous reviews indicate bloody hematemesis signifies more severe bleeding than coffee-grounds hematemesis. We assessed severity and outcomes related to bleeding symptoms in a prospective study.

methodsConsecutive patients presenting with hematemesis or melena were categorized as bloody emesis (N=1209), coffee-grounds emesis without bloody emesis (N=701), or melena without hematemesis (N=1069). We assessed bleeding severity (pulse, blood pressure) and predictors of outcome (hemoglobin, risk stratification scores) at presentation, and outcomes of bleeding episodes. The primary outcome was a composite of transfusion, intervention, or mortality.

resultsBloody and coffee-grounds emesis were similar in pulse ≥100 beats/min (35 vs. 37%), systolic blood pressure ≤100 mm Hg (12 vs. 12%), and hemoglobin ≤100 g/l (25 vs. 27%). Risk stratification scores were lower with bloody emesis. The composite end point was 34.7 vs. 38.2% for bloody vs. coffee-grounds emesis; mortality was 6.6 vs. 9.3%. Hemostatic intervention was more common (19.4 vs. 14.4%) with bloody emesis (due to a higher frequency of varices necessitating endoscopic therapy), as was rebleeding (7.8 vs. 4.5%). Outcomes were worse with hematemesis plus melena vs. isolated hematemesis for bloody (composite: 62.4 vs. 25.6%; hemostatic intervention: 36.5 vs. 13.8%) and coffee-grounds emesis (composite: 59.1 vs. 27.1%; hemostatic intervention: 26.4 vs. 8.1%).

conclusionsBloody emesis is not associated with more severe bleeding episodes at presentation or higher mortality than coffee-grounds emesis, but is associated with modestly higher rates of hemostatic intervention and rebleeding. Outcomes with hematemesis are worsened with concurrent melena. The presence of bloody emesis plus melena potentially could be considered in decisions regarding timing of endoscopy.
