Test | Result | Input parameters that will be tested for use in the three logistic regression models (result or unit) |
Relevant demographics | Age in years | Age (years) |
Physical examination of abdomen | Bladder palpable/not palpable | N/A |
Digital rectal examination | Prostate mild/moderate/severe enlargement Further assessment for prostate cancer required/not required | Prostate size (enlarged/not enlarged) |
Prostate Specfic Antigen (PSA) | PSA value—established thresholds for further assessment for prostate cancer (typically >3 ng/mL) or benign enlargement (typically ≥1.5 ng/mL). For clinical decision support tool: continuous variable in ng/mL | PSA (ng/mL) |
International Consultation on Incontinence Questionnaire Male Lower Urinary Tract Symptoms Short Form | Total score (0–52), voiding symptom score (0–20), storage symptom score (0–24). Individual symptom bother scores scored separately from symptom severity scores (0–130) | Storage/incontinence symptoms subscore Voiding symptoms subscore |
International Prostate Symptom Score questionnaires | Total score (0–35) | Storage/incontinence symptoms subscore Voiding symptoms subscore |
Bladder diary | Waking (day) time frequency, sleeping (night) time frequency, 24 hours voided volume, daytime voided volume, nocturnal voided volume, average volume voided each void, total urgency scores | Mean urgency score Mean 24 hours fluid intake (mL) |
Uroflowmetry (Flowtaker) | Maximum flow rate, voided volume against normal age-adjusted range. Single value in mL/s | Median maximum flow rate (mL/s) Median voided volume (mL) Mean 24 hours frequency Mean nocturia |
Post void residual | Residual volume against normal age-adjusted range. Single value in mL | Post void residual volume (mL) |
PSA, prostate-specific antigen.
