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

objectiveThis study evaluated the performance of the novel liquid fiducial marker (BioXmark®) in IGRT for bladder cancer.

methods20 patients with muscle invasive bladder cancer were entered in this prospective, single center, Phase I-II study. The novel BioXmark

resultsIn total, 76 markers were implanted in 20 patients. Of those, 60 (79% 95% CI ± 9%) were visible on CT scan. Due to the learning curve of the technique, the visibility improved in the last 75% of patients (86% visibility) compared to the first 25% of patients with 58% visibility. Concerning stability of the BioXmark

conclusionThe success rate of this novel fiducial marker was 79%, which is above the prospectively defined threshold rate. A distinct learning curve of the injection of the liquid marker was seen over the study period. The marker showed sustained visibility and positional stability during treatment phases and also appears to be safe and easy to inject. ADVANCES IN KNOWLEDGE: This novel liquid BioXmark® marker seems to be a very promising tool in daily-adaptive IGRT for bladder preserving chemoradiotherapy in muscle invasive bladder cancer.
