In Low 2025 et al., on machine-learning outcomes in IVDE, what was the most important predictor of outcome according to SHAP value analysis?

Thank you! Your submission has been received!
Oops! Something went wrong while submitting the form.
Correct. Lower T2W:L2 signal ratio was the strongest predictor of ambulation recovery.
Incorrect. The correct answer is T2W:L2 spinal cord signal ratio.
Lower T2W:L2 signal ratio was the strongest predictor of ambulation recovery.

🔍 Key Findings

The study included 162 deep-pain-negative dogs undergoing decompressive surgery (hemilaminectomy) for acute thoracolumbar intervertebral disc extrusion (IVDE).

Ambulatory recovery occurred in 53.1% of dogs (86/162).

The best performing machine-learning model was XGBoost, with an AUC of 0.9502 and accuracy of 89.1%, outperforming Ridge, AdaBoost, and Naive Bayes models.

Preoperative-only XGBoost models were less accurate, with AUC dropping to 0.8271 and accuracy to 71.9%.

Top predictive features (by SHAP analysis) included:

  1. T2-weighted to L2 spinal cord signal ratio (lower values predicted better outcome)
  2. Use of fenestration (presence associated with better recovery)
  3. Hospitalization duration
  4. Imaging modality used
  5. Duration of nonambulatory status

Machine learning provided better insight into prognostic factors than traditional statistical methods.

Oops! Something went wrong while submitting the form.
Correct. Half of the SA injections resulted in iatrogenic cartilage injury.
Incorrect. The correct answer is 50%.
Half of the SA injections resulted in iatrogenic cartilage injury.

🔍 Key Findings

  • Study Type: Cadaveric study using 36 paired canine shoulders (n = 18 per group: Subacromial [SA] and Supratubercular [ST])
  • Survey Results: 75% of clinicians preferred SA technique; 25% used ST
Accuracy Outcomes:
  • Complete accuracy: 50% (SA), 44% (ST) — no significant difference (p = .8)
  • Partial accuracy: 39% (SA), 50% (ST)
  • Complete miss: 11% (SA), 5.6% (ST)
Safety Outcomes (India Ink Assay for Iatrogenic Articular Cartilage Injury [IACI]):
  • Incidence of IACI:
    • SA: 50% (9/18 shoulders)
    • ST: 11% (2/18 shoulders) → statistically significant (p = .007)
  • Lesion depth: All ST lesions were partial-thickness; SA group had one full-thickness lesion (p = .027)
  • Location: Lesions found on glenoid and humeral head with even distribution in SA; only one each in ST
Clinical Implications:
  • Landmark-guided injections were ≤50% completely accurate, even by an experienced operator.
  • ST technique is safer with lower risk of cartilage damage, despite similar accuracy.
  • Findings support considering image-guided techniques to improve both safety and accuracy in clinical settings.

Thank you! Your submission has been received!
Oops! Something went wrong while submitting the form.
Correct. Dogs with complete CrCLR had significantly higher rates of MMI compared to those with partial tears.
Incorrect. The correct answer is Complete CrCLR.
Dogs with complete CrCLR had significantly higher rates of MMI compared to those with partial tears.

🔍 Key Findings

  • Medial meniscus injury (MMI) occurred in 36.3% of stifles with CrCLR in toy breed dogs (<5 kg)
  • Complete CrCLR was significantly associated with MMI (15.3% of complete vs. 3.4% of partial)
  • Severe lameness (grade 3) increased the likelihood of MMI compared to mild lameness (grade 1)
  • Higher body weight, even within the toy breed range, was positively associated with MMI
  • Yorkshire Terriers had the highest MMI incidence (55.6%), but this was not a significant independent factor due to multicollinearity
  • Arthroscopy identified more meniscal damage (including small radial tears and bucket-handle lesions) than gross examination might detect
  • MMI was classified as mild (radial tear) or severe (bucket-handle or flap) with implications for partial meniscectomy
  • Arthroscopy was used in all cases, underscoring its utility in small-breed stifle assessment
