Incidence of colorectal cancer in Iran: A systematic review and meta-analysis.
Review in Journal of research in medical sciences : the official journal of Isfahan University of Medical Sciences, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Background: The incidence of colorectal cancer (CRC) is rising in Iran, but reports vary across different regions due to diverse methods and data sources. This study aimed to conduct a systematic review and meta analysis to provide an overview of the incidence rate of CRC and its trend among Iranians in various provinces. Materials and Methods: A comprehensive literature search based on the Preferred Reporting Items for Systematic Reviews and Meta Analyses checklist was performed using national and international databases for papers published up to December 2023. CRC incidence rates were extracted from the numbers, crude rates, and age standardized rates (ASRs). A meta analysis was conducted to calculate the incidence rate and 95% confidence intervals (CIs) in subgroups of sex and province. Results: The initial database search retrieved 1287 papers, with 47 studies meeting the inclusion criteria after further screening. Overall, the trend of CRC incidence has been increasing, although a different pattern was observed in 2008. The pooled incidence rate of CRC was 8.46 (95% CI: 7.16-9.86) per 100,000 population before the publication of the annual continuous reports of the Iranian National Cancer Registry. The latest national data (2014-2017) indicated an ASR of approximately 15 per 100,000 population. Conclusion: The incidence of CRC in Iran is lower than the global average. However, inconsistent cancer registration policies and gaps in registration have hindered the ability to establish a reliable trend of CRC incidence over time.
