Based on all-time mean agreement, this item ranks 26 out of 135 qualifying items and is at the 81.3 percentile.
Qualifying items have 100 or more total observations. Higher means indicate more agreement and therefore a higher rank.
The daily slope annualized over 365.25 days is 0.413 points per year, with a 95% confidence interval of [-2.720, 3.546]. This short-window annualized number is provided for reference, but the observed-period change above is the primary trend estimate.
