A meta-analysis of the effects of energy intake on risk of digestive cancers

Figure 1 Flow diagram of the search strategy and study selection.

Figure 2 Summary relative risks of digestive cancers. A: The highest vs lowest category of energy intake from included cohorts; B: An increment of 1 MJ/day energy intake from included cohorts. Squares represent study-specific relative risk (RR) estimates (size of the square reflects the study-specific statistical weight, that is, the inverse of the variance); horizontal lines represent 95%CIs; diamonds represent summary RR estimates with corresponding 95%CIs.

Figure 3 Publication bias in the studies. Begg’s funnel plot indicating no publication bias in the studies included in this meta-analysis. No indication of publication bias was noted from both visualization of the funnel plot and Egger’s test.
