Fig. 2.

Effect of protein intake on hip fractures. Fixed-effect pooled hazard ratio (HR) analysis was used. Grey boxes represent the point estimates with the size of the box representing the weight of the study. Horizontal lines depict the length of the 95% CI. The diamond represents the pooled effect estimate.

* No exact sample size can be stated; the hazard ratio is the estimate of the effect at specific age levels (65 and 75 y) selected from a continuous distribution. Total sample size was 144,580 persons.
