The association between Planetary Health Diet Index and the risk of colorectal cancer: a case-control study.
Article in Scientific reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 papers, 1 of them a synthesis that pooled it.
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 Despite the beneficial effects of a plant-based diet on colorectal cancer (CRC), no study has yet investigated the relationship between a Planetary Health Diet Index (PHDI) and CRC in the Iranian population. Therefore, the present case-control study aimed to assess the relationship between this index and CRC. Methods The current research was conducted on 71 patients with CRC (case group) and 142 (control group) admitted to hospitals in Tehran, Iran. The PHDI (0-150 points) was calculated based on a semi-quantitative food frequency questionnaire. Conditional logistic regression was applied to evaluate the association between CRC and PHDI and its sub-scores. Results After adjusting for the role of potential confounders, lower odds of CRC were observed in the second tertile of the total ratio score (odds ratio (OR) = 0.334; 95% confidence interval (CI): 0.127-0.878, P = 0.026) and the last tertile of PHDI (OR = 0.407; 95% CI: 0.183-0.907, P = 0.028), total adequacy score (OR = 0.261; 95% CI: 0.110-0.622, P = 0.002), and total moderation score (OR = 0.380; 95% CI: 0.162-0.891, P = 0.026) in comparison to the first tertile of each index. Conclusions The current study's findings indicated a reverse relationship between PHDI, total adequacy, moderation, and ratio scores with the CRC odds. However, it is suggested that more research be performed in this field in the future to confirm the results of this study.
