05 and a p of 1.16, respectively. However, in both analyses, statistical significance was not reached. The occurrence of re-sprains at 12 month follow-up was not univariately associated with any of the 10 possible prognostic factors. Prognostic factors in non-recovered participants at 3 months follow-up: A total of 75 participants (74%) regarded themselves as not being recovered at 3 months follow-up. Of these 75 participants, 63 (84%) underwent the physical examination at 3 months follow-up and were included in the analysis. Seven of the potential prognostic factors were univariately associated with the

outcome recovery at 12 months. The final model ( Table 4) included the variables having re-sprains during 3 months of follow-up (β = -1.64, 95% CI -3.11 to -0.16) and having pain at rest at 3 months of follow-up (β = -0.69, 95% CI -1.08 to -0.29). Re-sprains at the 12 month Dasatinib molecular weight follow-up were not univariately associated with any of the potential prognostic factors at 3 months follow-up. Subjective instability at the 12 month follow-up

was univariately associated with four potential prognostic factors (pain during running, Ankle Function Score, recovery, and instability at 3-months follow-up). After backward selection, the final multivariate model included pain during running MK2206 (OR = 1.48, 95% CI 0.99 to 2.23) and instability (OR = 6.89, 95% CI 0.30 to 159.17) at 3 months of follow-up. However, these factors did not reach significance. Pain during running at the 12 month follow-up was univariately

associated with four potential prognostic factors (setting, pain during running, Ankle Function Score, and recovery at 3 months follow-up). The Ankle Function Score at 3 months follow-up (β = −0.05, 95% CI −0.09 to −0.01) and setting (β = 1.11, 95% CI −0.53 to 2.76) were included in the final multivariate model. However, only the Ankle Function Score was significantly associated with pain during running at the 12 month follow-up (β = −0.05, 95% CI −0.09 to −0.01). The participants who did not attend the physical examination were on average younger (36.5 vs 34.8 years), had a higher BMI (25.5 vs 26.5), and were more often treated with physical therapy (40% however vs 70%) than those who attended. There was no univariate association between any of the five possible prognostic factors from the 3 month follow-up and subjective recovery at the 12 month follow-up. Pain during running and the occurrence of re-sprains were both univariately, but not significantly, associated with the pressure threshold of the ventral malleoli lateralis. Finally, reported instability at the 12 month follow-up was univariately associated with the pressure thresholds of the ventral, distal, and dorsal malleoli lateralis. The final multivariate model included the pressure thresholds of the ventral (OR = 2.03, 95% CI 0.99 to 4.15) and dorsal malleoli lateralis (OR = 4.26, 95% CI 1.14 to 15.96); only the association with the dorsal malleoli lateralis was significant (p = 0.035).
