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
aim of the studyLarge melanoma tumour caused arterial remodelling of the distal part of the great saphenous vein. The metastasis occurred at the site where inguinal lymphadenectomy was previously performed and the proximal part of the great saphenous vein was resected.The aim of this study is the presentation of such a rare observation and literature overview concerning melanoma metastasis and possible stimuli causing remodelling of veins. MATERIAL AND
methodsMacroscopic and microscopic analyses of the large blood vessel that supplies melanoma were made. The size and structure of the blood vessel was compared with the regular great saphenous vein.
resultsThe macroscopic examinations allowed us to ascertain that the blood vessel that was identified intraoperatively as the great saphenous vein, has a thick, stiff wall. The microscopic analysis allowed demonstrated that the tunica media was typical for a muscular artery morphology. The morphometric analysis revealed that the blood vessel wall in the area of metastatic tumour was much thicker than the wall of a regular great saphenous vein.
conclusionsThis malignant melanoma skin metastases caused the recanalisation of the great saphenous vein the lumen of which was obliterated during the initial surgical treatment. The metastatic tumour supplied by large blood vessels grew extensively and caused arterial remodelling of the venous wall.
