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 and purpose: Previous studies have demonstrated that mini-ridge filters (MRF) can reduce beam delivery time in pencil beam scanning (PBS) proton therapy, but the effect on plan quality has not been analyzed in detail. Furthermore, the range modulation produced by the MRF may lead to an added benefit of reduced dose-averaged linear energy transfer (LET Materials and methods: Twenty patient plans from a range of treatment sites, including five deep inspiration breath hold (DIBH) patients, have been re-optimized with a Monte Carlo based MRF beam model and compared to the corresponding clinical plans in beam delivery time, clinical acceptability, and a range of dose and LET Results: The average delivery time per beam decreased from (96.7 ± 4.9) s to (75.3 ± 4.0) s (p < 0.001). DIBH patients saw a reduction from (82.8 ± 15.5) s to (70.4 ± 12.7) s. The average reduction in maximum LET Conclusions: MRFs can be used in PBS proton therapy to achieve a clinically relevant reduction in beam delivery time, and distal LET
