1 · What the graph read from 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.

2 · The registry

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

purposeColorectal cancer (CRC) is the third most common cancer worldwide and a leading cause of cancer-related mortality. Few studies have examined the preventive effects of dietary factors against CRC in Asian populations. Thus, this systematic review and meta-analysis aimed to synthesize and analyze current evidence on the relationships between various dietary components and the risk of CRC, colon cancer, and rectal cancer in Asian populations.

methodsWe included cohort studies from PubMed, Web of Science, Embase, and Scopus reporting an association between dietary factors and CRC risk in Asian populations. Relative risks (RRs) with 95% confidence intervals (CIs) were used to calculate the pooled risk estimates. Cochran's Q and I

resultsEighty-two publications met the inclusion criteria. The findings indicated that healthy dietary patterns were associated with a reduced risk of colon cancer (RR = 0.85, 95% CI, 0.74-0.97), and calcium intake was linked to a slight reduction in CRC risk (RR = 0.93, 95% CI, 0.86-1.00). Conversely, high total meat consumption was associated with increased risks of CRC (RR = 1.18, 95% CI, 1.03-1.34), and white meat intake was associated with a potential 40% increased risk of rectal cancer (RR = 1.40, 95% CI, 1.00-1.96).

conclusionsThis review suggested that healthy dietary patterns and calcium intake are associated with a lower risk of CRC in Asian populations. Nonetheless, additional studies are warranted to clarify the associations between dietary patterns and CRC risk.
