Figs. 1-A through 1-D Features of slide-based disclosure data.

Mean number of authors per publication in JBJS-A and JBJS-B original articles.

Number of disclosures per faculty member for the 439 faculty members who disclosed a conflict of interest. No conflicts of interest were disclosed by 1050 faculty members.

The relationship of relative claim payment to claim frequency for twelve claim types. The horizontal axis shows the number of claims of the indicated type divided by the total number of claims (464) expressed as a percentage. The vertical axis shows the total payment dollars for claims of the indicated type divided by the total payment for all claim types ($17,917,614) expressed as a percentage. Points above the line of identity indicate impact factors greater than 1 (i.e., those claim types where the payment is disproportionally high with respect to the claim frequency).

Interpretation of four confidence intervals for a difference trial (H0: M₁ – M₂ = 0; HA: M₁ – M₂ ≠ 0) and for an equivalence trial (H0: | M₁ – M₂ | > 10; HA: | M₁ – M₂ | ≤ 10). H0 is the null hypothesis, HA is the alternate hypothesis, M₁ and M₂ are the means for the two interventions, α is the significance level, and d is the equivalence threshold.
