Statistical analysis
The socio-demographic variables age and sex were registered. Other clinical characteristics were registered as
[26]
well, including total burned body surface area using the Lund and Browder chart , burn depth, compromised
body area, eschar removal prior to applying definitive autografts, number of days since admission until
definitive coverage, grafted anatomical area, donor sites, graft thickness, and complications. Scars were
assessed at month 1 and at month 12 based on the VSS. For qualitative variables, frequencies and percentages
were used, whereas for quantitative variables, mean, median and range were preferred. Microsoft Excel® was
used.

RESULTS
A total of 138 patients showing deep burns were admitted. They required definitive coverage with split-
thickness skin grafts, which were placed transversely. Of this group, most subjects were men [Figure 1], with a
mean age of 24.5 years (range: 7-74 years) [Figure 2]. Among injury mechanisms, the most common etiologic
factor was flame with 40% (n = 55), followed by electricity 13.7% (n = 19), scald 12.3% (n = 17), chemical agents
13% (n = 18), and other 21% (n = 29) [Table 1].
