From: How effective are clinical pre-farrowing risk assessment and the use of soft rubber mats in preventing shoulder ulcers in at-risk sows?

  Presence of shoulder ulcers (any score ≥ 1) n (%) Absence of shoulder ulcers n (%) Odds Ratio (95% Confidence Interval) p-value
Subgroup without rubber mat (n = 566)
At-risk group 63 (62.4) 38 (37.6) 5.55 (3.51, 8.76) <.0001
Non-at-risk group 107 (23.0) 358 (77.0) 1.0 (Ref.a)  
Subgroup under risk (n = 194)
Rubber mat group 44 (47.3) 49 (52.7) 0.54 (0.31, 0.96) 0.0358
No rubber mat group 63 (62.4) 38 (37.6) 1.0 (Ref.a)
