Defining the surgical management for non-colorectal liver metastases.
Article in Langenbeck's archives of surgery, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 1 paper.
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
backgroundSurgical resection is indicated for resectable colorectal liver metastases (CLM), but it is controversial for non-colorectal liver metastases (NCLM). This study aimed to compare survival outcomes of patients with resection of NCLM versus CLM and to identify prognostic factors for resection of NCLM.
methodsConsecutive patients who underwent surgical resection of liver metastases at Queen Mary Hospital, Hong Kong from January 1989 to December 2019 were retrospectively reviewed. Patients with resected NCLM were compared to those with CLM. Overall and recurrence-free survival were determined. Subgroup analyses with patients grouped according to the year of liver resection, from 1989 to 2004 and from 2005 to 2019, were conducted. Univariate and multivariate analyses were performed to identify prognostic factors.
resultsAmong 674 patients included, 151 (22.4%) had NCLM while 523 (77.6%) had CLM. There were no statistically significant differences in median overall survival (65.2 vs 43.6 months, p = 0.555) and recurrence-free survival (12.5 vs 11.7 months, p = 0.425). The 1-year, 3-year, 5-year and 10-year overall survival rates were 89.8% vs 91.5%, 59.4% vs 58.8%, 50.6% vs 38.7% and 34.1% vs 26.3% in NCLM and CLM groups, respectively. Subgroup analyses demonstrated no statistically significant difference in overall survival between resection of NCLM versus CLM in both time intervals. In the NCLM group, better overall survival was found in liver metastasis of gastrointestinal stromal tumour (GIST) origin (hazard ratio (HR) 0.138, p = 0.003) and with a longer time interval from resection of primary tumour to resection of NCLM (HR 0.982, p = 0.042). Poor prognostic factors were presence of blood transfusion (HR 5.588, p = 0.013) and post-operative complications of Clavien-Dindo Grade IIIa or above (HR 74.853, p = 0.003).
conclusionsSurgical resection of NCLM had comparable survival outcomes with CLM. With appropriate patient selection, the indication of liver resection could be expanded to NCLM.
