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
purposeThis study aimed to compare the perioperative efficiency, clinical outcomes, and radiographic outcomes of single-position O-arm navigation-assisted oblique lumbar interbody fusion (OLIF) 360 with those of dual-position traditional OLIF combined with Mazor Renaissance robot-assisted posterior fixation in patients with single-level lumbar spondylolisthesis.
methodsThis retrospective study included 110 patients with single-level L4-L5 lumbar spondylolisthesis who underwent surgery between March 2022 and January 2025. Of these, 50 patients underwent traditional OLIF combined with robot-assisted posterior fixation, and 60 underwent O-arm navigation-assisted OLIF 360. The severity of spondylolisthesis was classified according to the Meyerding grading system. Baseline characteristics; intraoperative parameters, including operative time, estimated blood loss, and radiation dose; postoperative outcomes, including length of hospital stay, clinical scores, and radiographic changes; and fusion rates and complications were compared between the two groups.
resultsAll patients completed 12 months of postoperative follow-up. Both groups showed significant improvements in Visual Analog Scale (VAS) and Oswestry Disability Index (ODI) scores compared with preoperative values (p < 0.05). No significant differences in VAS or ODI scores were observed between the groups at the 3- or 12-month follow-up. Compared with the robot-assisted group, the navigation-assisted group had a significantly shorter operative time, lower intraoperative blood loss, and lower total intraoperative radiation dose (p < 0.05). No significant intergroup differences were observed in the improvement rates of spinal canal area (SCA) or disc height (DH), changes in lumbar lordosis (LL), screw placement accuracy, or BSF-defined radiographic fusion rates.
conclusionO-arm navigation-assisted OLIF 360 was associated with improved perioperative efficiency, including shorter operative time, reduced intraoperative blood loss, and lower radiation exposure, while achieving clinical and radiographic outcomes comparable to those of traditional OLIF combined with robot-assisted posterior fixation. Screw placement accuracy and BSF-defined radiographic fusion rates were also similar between the two techniques.
