Semiannual change in proportions of call discrepancies between fellows and attendings
| Template | July-December (pA) | January-June (pB) | Difference | Hypothesis Tests (H0: pA = pB) |
|---|---|---|---|---|
| Great call | 0.7% | 0.9% | +0.2% | χ2 = 1.26, P value < .262 |
| Agree | 33.4% | 42.8% | +9.4% | χ2 = 106.17, P value < .0001 |
| Addition | 52.2% | 46.7% | –5.4% | χ2 = 33.57, P value < .0001 |
| Minor change | 12.3% | 8.2% | –3.7% | χ2 = 42.27, P value < .0001 |
| Major change | 1.4% | 0.9% | –0.5% | χ2 = 6.61, P value = .010 |
Note:—pA indicates proportions of call discrepancy during the first half of the academic year; pB, proportions of call discrepancy during the second half of the academic year; H0, null hypothesis.
