Relationship Between Visceral Metastases and Survival in Patients with Metastasis-related Spinal Cord Compression.
Article in Orthopaedic surgery, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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
objectiveTo investigate whether visceral metastases have a significant impact on survival in patients with metastasis-related spinal cord compression (MSCC), and to determine the difference in prognosis between patients with and without visceral metastases.
methodsThree institutional databases were searched to identify all patients who had undergone spinal surgery for spinal metastases between March 2002 and June 2010. Data on patient characteristics including pre- and post-operative medical conditions, were collected from medical records or by telephone follow-up. Survival data were obtained either from medical records or by searching a governmental cancer registry.
resultsThe mean age of study patients was 59.6 ± 10.5 years (range, 18-84 years), of whom 102 were male and 67 female. The median and mean postoperative survival times were 7.0 ± 0.5 (95% CI 6.0-8.0) months and 12.6 ± 1.2 (95% CI 10.1-15.0) months, respectively, in all patients, being 5.0 ± 0.5 (95% CI 4.0-6.0) months and 10.8 ± 2.4 (95% CI 6.1-15.5) months, respectively, for patients with visceral metastases and 7.0 ± 0.8 (95% CI 5.4-8.6) months and 13.0 ± 1.4 (95%CI 10.3-15.6) months, respectively, for patients without visceral metastases (P = 0.87). These survival times did not differ significantly between groups. Multivariate Cox proportional hazard regressions showed that visceral metastases had no statistically significant association with survival (P = 0.277), whereas rate of growth of primary tumor (P = 0.003), preoperative Karnofsky performance status (KPS) (P < 0.001), change in KPS (P < 0.001), and Frankel grade (P = 0.091) were independent prognostic factors in the whole cohort (P = 0.005). Changes in KPS (P = 0.001) and major complications (P = 0.003) were significantly associated with survival in patients with visceral metastases, whereas rate of growth of primary tumor (P = 0.016), change in KPS (P = 0.001), and preoperative KPS (P < 0.001) were significantly associated with survival in patients without visceral metastases.
conclusionsVisceral metastases do not appear to predict the prognosis of patients with MSCC; thus, more aggressive surgery should be considered in patients with MSCC who have visceral metastases. Additionally, prognostic factors differ according to visceral metastases status in these patients.
