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
Obturator vein usually terminates into the internal iliac vein. Its variations are the cause major bleeding problems in pelvic surgeries. We observed a rare variation in the termination of the right obturator vein. There was a duplication of right obturator vein. Both obturator veins entered the pelvic cavity through the obturator foramen and joined with two vesical veins to form a vesico-obturator plexus. This plexus surrounded the internal iliac artery and terminated into the internal iliac vein. Awareness of this rare variation could be of importance to anatomists, radiologists, gynaecologists, urologists, and orthopaedic surgeons. The plexus might lead to hazardous bleeding in pelvic lymph node clearance procedures, hernia surgeries, gynaecological and orthopaedic procedures in this region. The pelvic fractures too can provoke dramatic retroperitoneal hematomas related to these veins injuries.
