1 · What the graph read from 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.

2 · The registry

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

Focal prostate treatment (aka "male lumpectomy") has the potential to reduce invasiveness for prostate cancer patients. However, clinical deployment has been impeded by the difficulty of performing surgery through the urethra, which we hypothesize relates to both instrument dexterity and visualization limitations. To evaluate this hypothesis, in this paper we propose a system consisting of an endoscopic robot to enhance dexterity and an image-guidance display updated periodically during surgery based on MRI images. To evaluate the system, in this paper we compare four conditions: unaided manual resection using an endoscope, robot-aided surgery without image guidance, image guidance without the robot, and both robot and image guidance together. We find that while the robot and image guidance improve performance individually, the combination of the two provides the greatest improvement.
