The Outcomes of Surgical and Nonsurgical Treatment in Patients With Spinal Metastases of Lung Cancer: Protocol for a Prospective Cohort Study.
Article in JMIR research protocols, 2023. 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
backgroundSpinal metastases of lung cancer (SMLC) usually have a high degree of malignancy and require multimodality treatment. Patients with SMLC who experience clinical symptoms (eg, local pain, emerging or potential spinal instability, and progressive neurological dysfunction) require surgical treatment. However, there are discrepancies in the comparison of outcomes between surgical treatment and nonsurgical treatment.
objectiveThis paper presents the protocol for a study that aims to compare the clinical outcomes of surgical treatment and nonsurgical treatment for SMLC, explore the prognostic factors of SMLC, and establish a survival prediction model based on these prognostic factors.
methodsThis is a prospective cohort study, with an anticipated sample size of 240 patients (120 patients in the surgical group and 120 patients in the nonsurgical group). We will collect baseline data, including demographic, clinical, and radiological information, as well as data from patient-reported questionnaires. Patients will be followed up at 3, 6, 12, and 24 months after treatment, and survival status will be assessed every 3 months. The primary outcome is the overall survival period. Prognostic factors associated with overall survival will be analyzed by univariate and multivariate Cox proportional hazards regression. Odds ratios with 95% CIs will be presented. Statistical significance is set at P<.05.
resultsThis study has been approved by our institute's Medical Science Research Ethics Committee (IRB00006761-M2021085) after a careful audit of the design and content. Patient enrollment began in June 2022 at our hospital. Data collection is expected to be completed by early 2026, and the study results will be published by mid-2027.
conclusionsIn this study, we propose to set up a prospective cohort of patients with SMLC to investigate the outcomes between surgical treatment and nonsurgical treatment. We will explore the role of surgical treatment in SMLC and provide guidance to peer surgeons.
