Provocative angiography for lower gastrointestinal bleeding.
Article in Japanese journal of radiology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers, 1 of them a synthesis that pooled 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.
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
purposeThis study evaluated the results of provocative angiography performed to identify the site of hemorrhage in lower gastrointestinal bleeding to enable transcatheter arterial embolization. MATERIALS AND
methodsThe subjects of this study were 11 patients with acute lower gastrointestinal bleeding who underwent provocative angiography, after contrast agent extravasation could not be identified during conventional angiography. One patient underwent provocative angiography twice, making 12 cases of provocative angiography that were analyzed in this study. Urokinase was used in all cases. Heparin was administered in 2 cases, nicardipine in 3 cases, and alprostadil and isosorbide in 1 case each.
resultsContrast agent extravasation as a result of provocative angiography was observed in 6/12 cases (50%). Selective transcatheter arterial embolization was performed in all 6 cases in which extravasation was apparent, and it was technically successful in all six. Clinical success was achieved in 5 (83.3%) of the 6 cases in which technical success was achieved after provocative angiography.
conclusionProvocative angiography enabled the site of lower gastrointestinal bleeding to be identified in 6 of 12 cases (50.0%) when it could not be identified by conventional angiography, and in all 6 cases hemostasis was effectively achieved by embolization.
