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 correction of severe spinal deformities often requires osteotomy procedures such as laminectomy. This compromises the structural integrity of the spinal posterior column and may lead to complications including spinal instability, spinal cord exposure, and failure of bone graft fusion. A persistent clinical challenge is how to reconstruct the lamina to restore biomechanical stability while simultaneously protecting the spinal cord. Currently, no standardized artificial lamina repair material is available, and traditional metallic or single-component bioabsorbable materials cannot adequately balance biocompatibility, mechanical support, and physiological healing. To address this need, we designed and fabricated a novel multifunctional split-type porous biomimetic absorbable modified PLA-HA lamina (MSPBA mPLA-HA lamina). In a sheep laminectomy model, the implant-bone interface bone volume fraction in the experimental group reached 74.6% and was significantly higher than that in the control group, while the mechanical stiffness of the reconstructed lamina was comparable to that of native sheep lumbar laminae. These findings suggest that the implant can support lamina reconstruction and that its porous architecture may provide a structural basis for reducing local epidural compression. As a bioactive absorbable construct, the MSPBA mPLA-HA lamina may represent a promising strategy for more physiologically compatible spinal posterior column reconstruction.
