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

backgroundSurgery is the main modality of comprehensive tumor treatment, and there are fewer studies on surgery in lung cancer patients with liver metastases.

methodsIn this study, clinical data on lung cancer patients with liver metastases were obtained from the Surveillance, Epidemiology, and End Results (SEER) database. Patients treated with cancer-directed surgery (CDS) by Propensity Score Matching (PSM) are matched 1:1 to patients not treated with CDS. The impact of CDS treatment and clinical factors on patient prognosis was explored Kaplan-Meier survival analysis, univariate and multivariate Cox analysis, and Cox risk proportional regression models.

resultsA total of 6,632 lung cancer patients with liver metastases were included in this study, including 83 patients treated with CDS (1.25%) and 6549 patients not treated with CDS (98.75%). By PSM matching, 83 patients not treated with CDS were obtained. Survival analysis showed that the median survival was 9 months (95% CI 7-15 months) in the CDS group, compared to 3 months (95% CI 2-6 months) in the No-CDS group. Cox risk proportional regression models indicated that No-CDS, male and N2-N3 staging were prognostic risk factors, whereas chemotherapy were prognostic protective factors. In addition, univariate and multivariate Cox analyses showed that No-CDS and men were independent prognostic risk factors, whereas chemotherapy were independent prognostic protective factors.

conclusionsOur findings suggest that CDS treatment can improve the prognosis of patients with lung cancer with liver metastases, which will provide a reference for further randomized controlled clinical trials.
