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 Colonic angiodysplasia is an acquired arteriovenous malformation that mainly occurs in older patients and is routinely managed using argon plasma coagulation (APC). Among the available endoscopic treatment options for angiodysplasia, APC is the most widely used. However, repeat endoscopy may be required because of post-treatment rebleeding after APC. Furthermore, the high prevalence of angiodysplasia in the right colon complicates treatment with APC because ablation in the right colon is associated with a higher risk of gastrointestinal perforation. A well-documented consensus on the endoscopic treatment of colonic angiodysplasia has not been established, given wide variation in treatment strategies. The efficacy of APC remains unclear due to the lack of prospective studies comparing clinical outcomes, including post-treatment rebleeding rates. CASE REPORT This report describes a 73-year-old woman with anemia caused by a colonic angiodysplasia of the cecum that resulted in spontaneous hemorrhage. We successfully managed the case using endoscopic mucosal resection (EMR) and APC, upon recurrence of angiodysplasia after APC. Treatment using EMR combined with clipping showed no angiodysplasia recurrence. CONCLUSIONS This report suggests that EMR has the potential to serve as a standard treatment option for colonic angiodysplasia, similar to APC. The additional use of clipping in combination with APC or EMR may prevent rebleeding, particularly in patients with risk factors for angiodysplasia-induced hemorrhage.
