Outcomes of surgical treatments for sacral metastases.
Article in Surgical neurology international, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Sacral metastases can cause severe pain, neurologic deficits, and sacroiliac instability, leading to substantial functional impairment. Although surgery is used for symptom palliation, patient-reported outcomes (PROs) following minimally invasive spinopelvic fixation remain poorly characterized. Methods: We retrospectively reviewed 10 patients (median age, 63 years) who underwent surgery for sacral metastases between 2015 and 2022. Procedures included posterior decompression alone or posterior decompression with minimally invasive spinopelvic fixation for sacroiliac instability. Eastern Cooperative Oncology Group (ECOG) performance status and PRO measurement information system (PROMIS) pain interference (PI), physical function (PF), and Depression scores were collected preoperatively and at 3 months postoperatively. Overall survival was estimated using Kaplan-Meier analysis. Results: Four patients underwent posterior decompression alone, and six underwent decompression with minimally invasive spinopelvic fixation. Mean ECOG improved from 2.5 preoperatively to 1.6 at 3 months ( Conclusion: Surgery for sacral metastases provides clinically meaningful pain relief and short-term functional improvement. Minimally invasive spinopelvic fixation is a feasible option for patients with sacroiliac instability and supports durable symptom palliation.
