Since 2009, all pediatric LRD kidney transplantations were performed at our center.
Patients were divided into two groups; LRD and LURD.
Twenty-seven patients (38.5%) received LRD transplants, 64.2% of these were performed locally.
HLA A, B, DR alleles were available for 82.1% (n = 23) of LRD patients, 73.9% (n = 17) had three matches (haplotype), 13.0% (n = 3) had four matches, 8.6% (n = 2) had six matches, and 4.3% (n = 1) had one match.
Sixty-four percent of our LRD transplantation patients received IL2-R blocker as induction agents compared to only 26.1% of LURD transplant patients.
Children who received LURD kidney transplant had high surgical complications at 42.8% compared to 17.8% for LRD recipients (p-value = 0.005).
Columns 1 and 3 report cross-section estimates for the 1993 (column 1) and 1996 (column 3) data that could be successfully matched to the 1977 LRD. Columns 2 and 4 rep ort the first-difference estimates using the 1977 data as well.
(11.) Although the sampling frame for NES I is the SSEL, the establishment size restrictions in the NES's and over-sampling or certainty sampling of large establishments lead to considerable overlap between NES I and the 1993 LRD. Thus, we obtain approximately 40% of matches from the 1993 LRD, and 60% from the 1992 LRD (which includes the entire Census of Manufactures).
(13.) We also analyzed a full 1993 cross-section with 665 observations, to incorporate information on work force and plant-level controls not available in the LRD, for which we discuss a limited set of results.
(22.) We also examined results using the full 1993 cross-section with additional controls added for work force characteristics (and other variables), which are not available in the 1977 LRD (or other years of the LRD).
(1993 or 1992 data substituted from LRD) Constructed variable: LBRCOST = total labor costs / TOT WRKRS.
The other control variables included are production function inputs, establishment age (for 1993 only), and dummy variables for two-digit industries, whether the plant belongs to a multi-plant firm, and whether in the 1993 data the labor cost and employment data came from the 1992 LRD. Descriptive statistics for these variables are reported in Appendix Table A2, and estimated coefficients of these variables for the specifications corresponding to those in this table and Tables 4 and 5, but excluding the work practice variables, are reported in Appendix Table A3.
