Low dietary calcium intake leads to a higher colorectal cancer burden in countries with low social development: findings from the Global Burden of Disease Study 2021.

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: Numerous studies have demonstrated that individuals with low calcium intake are at increased risk of developing colorectal cancer (CRC), and calcium intake exhibits significant global variation. However, a comprehensive analysis of the diet low in calcium-attributable colorectal cancer (DLCACRC) disease burden remains lacking. Objective: This study aimed to investigate the global distribution and temporal trends of DLCACRC from 1990 to 2021, providing evidence to support the development of evidence-based nutrition policies. Methods: Data on deaths, disability-adjusted life years (DALYs), mortality rates, and DALYs of DLCACRC between 1990 and 2021 were extracted from the GBD database. Age-standardized data were utilized to facilitate comparisons across regions and countries. Joinpoint regression analysis was conducted to assess temporal patterns in disease burden. Estimated annual percentage changes (EAPCs) were calculated to quantify the rate of change in relevant indicators. Pearson correlation analysis was performed to determine the relationship between the disease burden and the Social Development Index (SDI). Result: In 2021, the global age-standardized mortality rate (ASMR) of DLCACRC reached 1.06 (95% CI: 0.77-1.33), while the age-standardized disability-adjusted life year rate (ASDR) was 24.7 (95% CI: 18.17-31.02). These metrics demonstrated a downward trend, showing 31.3 and 33.3% reductions, respectively, compared to 1990. The most rapid reductions in ASMR and ASDR were occurred during 2004 and 2007, with annual percentage change (APC) of -2.12 (95% CI: -2.80-1.43) and -2.29 (95% CI: -2.92-1.65), respectively. Significant differences in disease burden were observed across countries and regions, with Southeast Asia reporting the highest ASMR and ASDR of DLCACRC. At the national level, Zambia recorded the highest ASMR and ASDR. Women experienced a higher disease burden than men, and the disease burden was positively correlated with age. Conclusion: From 1990 to 2021, the global disease burden of DLCACRC declined, although substantial regional disparities persist. Governments in these regions should adopt targeted strategies to enhance calcium intake among residents, thereby alleviating the disease burden. Particular attention should be given to women and older adults.
