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
The diagnostics and laser infrastructure of the Soft X-ray Port (SXP) at the European X-ray Free Electron Laser are presented. Designed as a supplementary open port, SXP aims to enhance the research capabilities alongside the existing baseline instruments at the SASE3 soft X-ray undulator exploiting the high repetition rate operation enabled by superconducting acceleration cavities. These instruments already support studies in atomic, molecular and non-linear optics (SQS), as well as condensed matter physics (SCS). The inception of SXP is largely motivated by the community involved in time-resolved X-ray photoelectron spectroscopy (tr-XPES), focusing on material science dynamics at surfaces and interfaces. The dedicated endstation equipped with a time-of-flight momentum microscope allows for simultaneous recording of energy- and angle-resolved photoelectron distributions in a pump-probe setting, employing two synchronized femtosecond laser systems meant to cover a broad spectrum from the infrared to the extreme ultraviolet region. The alignment laser system, pump-probe laser transport, including the in-coupling optics, and the installed photon arrival-time monitor are described. Under the present operating conditions, however, the photon arrival-time monitor does not yet provide routine single-shot timing corrections, so the currently demonstrated temporal benchmark is obtained in situ at the tr-XPES endstation. Measurements on a patterned Au reference sample show that the laser spot sizes can be characterized directly and that sidebands yield an X-ray/optical cross-correlation of about 58 fs (FWHM). These measurements define the spatial and temporal instrument response currently achieved for pump-probe experiments at SXP.
