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
Recanalization of chronic venous occlusions is sometimes technically challenging. We present a rare case of venous occlusion, due to previous intravenous femoral drug use, with a fibrotic perivenous tissue in the groin, hard to cross. This patient presented with severe venous claudication with an active ulcer. After failure of conventional attempts, we opted for a more aggressive strategy using a modified Chiba needle (Cook Medical)-assisted sharp recanalization technique. We achieved initial technical success in recanalization, but thrombosis eventually recurred because of residual compression on the created extravascular tract. However, the patient showed clinical improvement, and we chose not to attempt another procedure. This case report emphasizes the use of this unconventional crossing technique and provides a detailed, didactic description of the equipment and procedural steps, aiming to illustrate its potential role and limitations in complex venous recanalization.
