1 · What the graph read from it

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.

2 · The registry

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 clinical value of using a spine robot to guide unilateral PVP for lumbar Kümmell's disease has not been fully established. The traditional bilateral pedicle PVP tends to cause suboptimal cement distribution, longer operation time, and increased exposure to radiation. To compare the safety and effectiveness of spine robot-assisted modified unilateral PVP with conventional bilateral pedicle puncture PVP. We performed a single-blind randomized trial including 110 patients with lumbar Kümmell's disease. Patients were assigned in equal numbers to robot-assisted modified unilateral PVP or manual bilateral pedicle PVP. The main endpoint was 12-month Cobb angle change. Additional endpoints included AVH, PVH, WA, VAS, ODI, operative indicators, and complications. At all time points after the operation, the robot-assisted group showed significantly higher reductions in Cobb angle, WA, VAS, and ODI and significantly better preservation of AVH and PVH (all P < 0.05). Operative time (47.15 ± 8.26 vs. 69.25 ± 10.94 min), blood loss (10.29 ± 2.87 vs. 25.31 ± 4.43 mL), and fluoroscopy times (9.80 ± 1.59 vs. 26.24 ± 4.74) are significantly reduced in the robot-assisted group. The rate of bone cement leakage and vertebral recollapse also decreased. Robot-assisted modified unilateral PVP has better long-term correction of kyphotic deformation, reduced complications, and higher procedural efficacy compared to utilizing conventional bilateral PVP under the limitation of single-center single-blind trial. It is a more precise and minimally invasive approach for treating lumbar Kümmell's disease.
