Table 1. Decay time and associated metrics together with manual categorization of capillary contents for both “outlier” and “control” vessel-epochs.
Capillary contents | ||||
---|---|---|---|---|
Parameter | Cell agg. or WBC | Plasma length | Normal (v < 1 mm/s) | Normal (v > 1 mm/s) |
Outlier epochs (n) | 208 | 160 | 103 | 51 |
Control epochs (n) | 4 | 14 | 37 | 340 |
Total epochs (n) | 212 | 174 | 140 | 391 |
Rate (sensitivity or specificity) | 0.98 (208/212) | 0.92 (160/174) | 0.74 (103/140) | 0.87 (340/391) |
Unique segments (n) | 45 | 39 | 40 | 73 |
Velocity (mm/s for seg. in epoch) | 1.8 ± 0.7 | 1.4 ± 0.5 | 0.7 ± 0.2 | 2.0 ± 0.8 |
Average velocity (mm/s for seg.) | 2.0 ± 0.4 | 1.7 ± 0.4 | 0.9 ± 0.3 | 1.9 ± 0.7 |
Field velocity (mm/s in epoch) | 1.9 ± 0.4 | 2.0 ± 0.4 | 1.4 ± 0.3 | 1.8 ± 0.4 |
“Sheathing” (ratio for seg. in epoch) | 1.44 ± 0.38 | 1.38 ± 0.41 | 1.29 ± 0.27 | 1.02 ± 0.06 |
Average “sheathing” (ratio for seg.) | 1.12 ± 0.12 | 1.13 ± 0.13 | 1.22 ± 0.24 | 1.01 ± 0.03 |
Contents were rated as “cell”, “plasma” or “neither” by a blinded observer. Ratings of “neither” were broken down into slow or not-slow with a velocity criterion of 1 mm/sec. Values accompanied by uncertainty symbols indicate mean ± standard deviation.
