Figures

  • Fig. 1. Recommendations from regulatory agencies for appropriate descriptors and outcomes for translational large animal studies in cartilage repair.

    Color scheme indicates whether the documents provide detailed (green), loose (yellow), or no (red) recommendations in a category.

  • Fig. 2. Literature search, screening, and eligibility testing using the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines (29).
  • Fig. 3. Array depiction and quantification of adherence to guidance document recommendations.

    Each row indicates a different category (top, descriptors; bottom, outcomes), whereas each column represents an individual study. Green indicates full adherence, red indicates nonadherence, and yellow indicates partial adherence. Bars at right show average percentage adherence across all studies in a given category.

  • Fig. 4. Study number and adherence as a function of year, species, study duration, and number of animals.

    (A) Number of studies per year (*through 18 April 2014). (B) Overall adherence by study and year. Vertical lines indicate the time of publication of the *ASTM, #FDA, and §EMA documents. Regression shows slight increase in overall adherence with time (P = 0.004, R2 = 0.07, slope = 0.63%/year). (C) Mean adherence per year, broken out into overall, study descriptors, and study outcomes. Study descriptors were reported at a higher level than study outcomes. Standard deviation is shown for overall adherence only. (D) Adherence (in percent) across species (white bars, study descriptors; hatched bars, study outcomes; black bars, overall adherence; *P < 0.05). (E and F) Correlation between overall adherence and study duration (R2 = 0.075, P = 0.003) (E) and overall adherence and the number of animals (R2 < 0.001, P = 0.994) (F).
