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
background and purposeLung cancer is the leading cause of cancer-related mortality in Greenland. Since 2004, medical treatment of lung cancer has been available in Greenland. However, both diagnostic work-up and treatment logistics are hampered by the lack of medical services in smaller settlements, the infrastructure, and extreme arctic weather conditions. Clinico-pathological data and assessment of treatment outcome in lung cancer in Greenland have not been carried out since 2015. This study aims to provide an analysis of Greenlandic patients with non-small cell lung cancer (NSCLC) from 2015 to 2020, compared to the cohort from the 2015 study. We focus on diagnostics, patient and treatment characteristics, and survival rates. Additionally, we include new data on treatment-related factors and diagnostic delays. Patients/material: Clinical-, pathological-, genomic data, tuberculosis status and survival were retrieved from the medical journal.
resultsA total of 163 patients were identified. Survival had improved in stage I, III, and IV, and early-stage disease was more often diagnosed as compared to the 2015 cohort. Molecular alterations and PD-L1 expressing tumors were comparable between Greenlandic and Danish patients. Diagnostic delay was a major concern.
interpretationWhile NSCLC survival in Greenland has improved over the past decade, significant challenges remain. The trend towards diagnosing more stage IA-IIIA patients and the recent improvements in diagnostic and therapeutic options in Greenland are expected to translate into a better prognosis in the coming years. Addressing diagnostic delays and enhancing treatment options are crucial steps toward improving outcomes for NSCLC patients in Greenland.
