Low Income Has a Negative Effect on Survival Following Diagnosis of Metastatic Colorectal Cancer-A Population-Based Cohort Study.
Article in Cancer medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundTreatment for metastatic colorectal cancer (mCRC) has seen great advances but may not be equally available for all patients.
aimTo evaluate the impact of socioeconomic status on cancer-specific survival after diagnosis of mCRC, with emphasis on potential temporal trends in the effect of income.
methodsThis population-based cohort study, based on 90,620 patients diagnosed with colorectal cancer in Sweden during 2007-2021 and registered in CRCBaSe, identified 33,498 patients with mCRC through 2022. We used relative survival to estimate excess mortality rate ratios (EMRRs) with 95% confidence intervals (CIs) comparing net survival by income quartiles, adjusting for sex, age, calendar year, education, marital status and birth country.
resultsOne-year relative survival improved from 55% in 2007-2012 to 63% in 2017-2022. In the first years after the diagnosis of metastases there was an income gradient with the biggest contrast between high-income and low-income patients (EMRR (95% CI) at one year: 0.84 (0.81-0.88)). Year of mCRC diagnosis did not alter the effect of income on survival.
conclusionsDespite significant improvements in cancer-specific survival for mCRC over the last decades, socioeconomic disparities, particularly based on income, continue to affect survival outcomes. The impact of income remains consistent from 2007 to 2021.
