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

backgroundFew studies have addressed the impact of palliative surgery for cervical spine metastasis on patients' performance status (PS) and quality of life (QOL). We investigated the surgical outcomes of patients with cervical spine metastasis and the risk factors for a poor outcome with a focus on the PS and QOL.

methodsWe prospectively analyzed patients with cervical spine metastasis who underwent palliative surgery from 2013 to 2018. The Eastern Cooperative Oncology Group PS (ECOGPS) and EuroQol 5-Dimension (EQ5D) score were assessed at study enrollment and 1, 3, and 6 months postoperatively. Neurological function was evaluated with Frankel grading. Univariate and multivariate analyses were performed to identify the risk factors for a poor surgical outcome, defined as no improvement or deterioration after improvement of the ECOGPS or EQ5D score within 3 months.

resultsForty-six patients (mean age, 67.5 ± 11.7 years) were enrolled. Twelve postoperative complications occurred in 11 (23.9%) patients. The median ECOGPS improved from PS3 at study enrolment to PS2 at 1 month and PS1 at 3 and 6 months postoperatively. The mean EQ5D score improved from 0.085 ± 0.487 at study enrolment to 0.658 ± 0.356 at 1 month and 0.753 ± 0.312 at 3 months. A poor outcome was observed in 18 (39.1%) patients. The univariate analysis showed that variables with a P value of < 0.10 were sex (male), the revised Tokuhashi score, the new Katagiri score, the level of the main lesion, and the Frankel grade at baseline. The multivariate analysis identified the level of the main lesion (cervicothoracic junction) as the significant risk factor (odds ratio, 5.00; P = 0.025).

conclusionsPalliative surgery for cervical spine metastasis improved the PS and QOL, but a cervicothoracic junction lesion could be a risk factor for a poor outcome.
