Proportion of readings for each slide category correctly diagnosed as non-NGU or NGU
| Microscopist | % (n) of readings for negative slides correctly diagnosed as non-NGU | % (n) of readings for low grade slides correctly diagnosed as NGU | % (n) of readings for high grade slides correctly diagnosed as NGU | |||
|---|---|---|---|---|---|---|
| SM standard (n = 39/40*) | Consensus standard (n = 45/46*) | SM standard (n = 22) | Consensus standard (n = 24) | SM standard (n = 30) | Consensus standard (n = 22) | |
| *Denominators vary because one slide was read once by all microscopists but misplaced before the second reading could be performed by six of the microscopists. | ||||||
