Figure 1. Study-specific and pooled multivariable relative risks (95% CI) of ALS for 1g/day increase in n-3 PUFA.

Figure 1

Study-specific and pooled multivariable relative risk (RR) and 95% confidence interval (CI) of amyotrophic lateral sclerosis for a 1g change in intake of n-3 PUFA. The squares and horizontal lines correspond to the study specific multivariable RR and 95% CI, respectively. The inverse of the variance is used to calculate study weight and is represented by the area of the square. The diamond displays the pooled multivariable RR and 95% CI. We observed no significant effect modification by gender (P=0.74).
