Association between remnant cholesterol and colorectal cancer risk in Korea: a nationwide population-based study.
Article in The Korean journal of internal medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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/
aimsRemnant cholesterol (RC) has emerged as a novel lipid marker with potential implications in cardiovascular and metabolic diseases. However, its association with colorectal cancer (CRC) remains unclear.
methodsWe conducted a retrospective cohort study using data from 364,626 Korean adults who underwent a national health screening between 2012 and 2013. RC and other lipid parameters were categorized into quartiles. Participants were followed up until CRC diagnosis, death, or December 31, 2019. Cox proportional hazards models were used to estimate the adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) after controlling for demographic, clinical, and lifestyle factors.
resultsCRC incidence increased from 1.75 to 2.25 per 1,000 person-years across the RC quartiles. When compared with Q1, adjusted HRs were 1.08 (95% CI, 0.96-1.21) in Q2, 1.13 (1.01-1.26) in Q3, and 1.21 (1.08-1.35) in Q4. A similar trend was observed for triglycerides but not for low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, or total cholesterol. In the subgroup analyses, the association between RC and CRC was stronger in participants aged ≥ 65 years and those with a body mass index < 23 kg/m2.
conclusionElevated RC levels were independently associated with an increased risk of CRC. Thus, RC may serve as a useful biomarker for CRC risk stratification beyond traditional lipid parameters.
