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
Background: The purpose of this study is to determine the effect of the type of I-125 radioactive source on dose distribution in the planning process of ultra-low dose rate (uLDR) prostate brachytherapy. Material and methods: 7 patients who had undergone brachytherapy in our center were included in the study. Dose in five geometrical points were analyzed for 12 types of implants that are available on the market. The plans were originally calculated for S17plus implant model (Eckert & Ziegler Medical). Point dose calculations were performed using RadCalc (LAP) software. Results: The differences in doses for individual points were significant. The largest differences were observed at the point located in the center of the patients' urethra and between BestMedical 2301 (highest doses for each point) and IsoStar (lowest doses) implants. Conclusions: The choice of implant manufacturer strongly influences what dose distribution will be obtained for the prostate. It is possible to obtain satisfactory plans that meet the dosimetric criteria for each type of implant, but the positioning of each source will vary significantly.
