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
introductionLumbar degenerative disease (LDD) is increasingly common, and causes back and leg pain that impairs quality of life. Lumbar interbody fusion (LIF) is effective for patients with neural compression and segmental instability. Unilateral biportal endoscopic LIF (UBE-LIF) allows for minimally-invasive decompression and fixation, while navigation- and robot-assisted systems improve pedicle screw accuracy and intraoperative guidance.
aimThis study compared perioperative outcomes and clinical efficacy of navigation-assisted vs robot-assisted single-level UBE-LIF. MATERIALS AND
methodsPatients with single-level LDD who underwent navigation-assisted (Na group; n = 23) or robot-assisted (Ra group; n = 29) UBE-LIF between January 2020 and December 2024 were retrospectively enrolled. Clinical outcomes were assessed using the Numeric Rating Scale, Oswestry Disability Index, and modified MacNab criteria. Pedicle screw placement and radiological parameters, including disc height, lumbar lordosis, and segmental lumbar lordosis, were evaluated, and IF was assessed at 12 months postoperatively.
resultsEndoscopic operative time was shorter in the Na group than in the Ra group (116.74 vs 127.86 min;
conclusionsNavigation- and robot-assisted UBE-LIF are safe and effective procedures. Robot-assisted surgery offers higher screw accuracy and faster insertion, while the navigation-assisted approach reduces endoscopic operating time. Clinical outcomes and fusion rates between the 2 techniques are similar.
