Neurality Impact

Pre window: up to 6 months immediately before rollout (minimum 3 required). Months with &lt;8 hygienist provider-days are excluded for the hygiene metric.
Post window: all months from rollout month forward (through April 2026).
Per-practice test: Welch's two-sided t-test on monthly values. Significance bands: p&lt;.05 = significant, p&lt;.10 = marginal.
Cohen's d: standardized effect size (0.2 small, 0.5 medium, 0.8 large), pooled SD.
Network paired t-test: across practices, of the per-practice (postMean − preMean) difference. Tests whether the average per-practice shift differs from zero.
Sign test: non-parametric — counts how many practices moved up vs down, tests against 50/50 chance.
Caveat: practices rolled out after Dec 2025 (~30 of 99) have ≤4 post months — low per-practice statistical power. They're still counted in the network sign test (direction only) but per-practice tests rarely flag significance.

Did Neurality move hygiene visits per hygienist per day and new patients per month across 99 practices?
