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

backgroundTraditional unilateral biportal endoscopic (UBE) decompression for two-level adjacent lumbar spinal stenosis (LSS) often requires a third incision, potentially leading to increased blood loss, longer operative time, and greater reliance on fluoroscopy. To address these limitations, we propose a novel sliding approach UBE (S-UBE) for treating two-level adjacent LSS. This study presents the technique and its preliminary clinical outcomes.

methodsIn this retrospective study, 41 patients with two-level adjacent LSS were treated with S-UBE between April 2021 and October 2023. Treatment outcomes were evaluated based on operative time, blood loss, surgical complications, hospital stay duration, visual analog scale (VAS) scores, Oswestry Disability Index (ODI), and modified MacNab criteria. Radiological evaluations were performed at regular intervals during follow-up.

resultsAll patients successfully underwent surgery with the S-UBE technique. The mean operative time was 118.27 ± 11.79 min, average blood loss was 92.46 ± 11.75 ml, and the mean hospital stay was 5.20 ± 1.45 days. No major surgical complications occurred, though two patients experienced transient numbness and pain in their lower limbs, which recovered from conservative treatment. Postoperative VAS scores were significantly lower (P < 0.05), while ODI scores improved significantly compared to preoperative values (P < 0.05). The excellent-to-good outcome rate based on the modified MacNab criteria was 95.12%. Facet joint preservation rates were 84.76% at the L3-L4-L5 segment and 88.38% at the L4-L5-S1 segment. No cases of lumbar instability were observed during follow-up.

conclusionThe S-UBE technique is an effective alternative for treating two-level adjacent LSS, offering a minimally invasive solution with only two skin incisions. This approach demonstrates promising clinical outcomes, including reduced operative time, minimal blood loss, and high facet joint preservation rates.
