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

purposePrevious epidemiological studies on egg consumption and the risk of gastrointestinal (GI) neoplasms suggest a positive association; however, data are limited and the evidence remains controversial. This study aims to investigate and quantify the potential dose-response relationship with an evaluation of cancer site-specific differences.

methodsRelevant studies were identified after the literature search via electronic databases until January 2014. Subgroup analysis for serving portions was performed using two standardized classification methods: (1) less than 3, or 3 or more eggs per week; (2) less than 3, 3-5, or more than 5 eggs per week. Method two excludes studies that only reported consumption frequency. Pooled adjusted odds ratios (ORs) comparing highest and lowest categories of dietary pattern scores were calculated using a random-effects model.

resultsThirty-seven case-control and seven cohort studies were included for meta-analysis, which contained a total of 424,867 participants and 18,852 GI neoplasm cases. The combined odds ratio (OR) was calculated to 1.15 (95% CI 1.09-1.22; p value heterogeneity <0.001), showing only a slight increase in risk. The correlation was stronger for colon cancers 1.29 (95% CI 1.14-1.46; p value heterogeneity <0.22). Dose-response analysis revealed similar results with stratification methods, and the ORs for an intake of <3 and ≥3 eggs per week were 1.14 (95% CI 1.07-1.22; p value heterogeneity = 0.38) and 1.25 (95% CI 1.14-1.38; p value heterogeneity = 0.25), respectively. With method 2, the ORs for an intake of <3, 3-5, and >5 eggs per week were 1.13 (95% CI 1.06-1.21; p value heterogeneity = 0.25), 1.14 (95% CI 1.01-1.29; p value heterogeneity = 0.06), and 1.19 (95% CI 1.01-1.39; p value heterogeneity <0.001), respectively.

conclusionThis study provides evidence that egg consumption is associated with a positive dose-response association with the development of GI neoplasms.
