Analyses were performed using trend statistics of Mantel-Haenszel test
and Student's t-tests where appropriate to test for significant difference in observed proportion between the cases and controls.
Differences in binary outcomes between the focal hospital and matched controls were tested using a stratified Mantel-Haenszel test
. Cost, LOS, and anesthesia time are reported using m-estimation (Huber 1981; Hampel et al.
The Mantel-Haenszel test
of homogeneity of risk ratios was used to assess whether the RR differed by race/ ethnicity.
We compared response rates between treatment arms using the exact conditional version of the Mantel-Haenszel test
to control for clustering by clinical center.
The DIF analyses were performed using the Mantel-Haenszel test
(MH) and the generalized MH test (Mantel & Haenszel, 1959).
* Statistically significant association, Mantel-Haenszel test
The most common MH statistics used for DIF detection are: the MH chi-square statistic ([X.sup.2.sub.MH]; Holland & Thayer, 1988; Mantel & Haenszel, 1959), the generalized Mantel-Haenszel test
(GMH, Mantel & Haenszel, 1959; Zwick, Donoghue, & Grima, 1993) and the Mantel test (MT; Mantel, 1963; Zwick et al., 1993).
Originally published as Test item bias in 1983, the second edition focuses on the Mantel-Haenszel test
, IRT-based methods, and logistic regression.
Statistical analysis, Mantel-Haenszel test
. Statistically significant differences were observed between group AUT and group II (P=0.002).
Trend over time in overall prevalence was evaluated using the Mantel-Haenszel test
Data were analyzed by the Mantel-Haenszel test
and [chi square] test with SPSS version 10.0 software (SPSS, Chicago, IL, USA).
The results from the Mantel-Haenszel test
[ILLUSTRATION FOR FIGURE 2 OMITTED] show that there was no difference in galling rate here between wild plants and those transplanted back to their original site, after the effects of site had been removed (Mantel-Haenszel [[Chi].sup.2] = 0.824; P = 0.364).
