“…In our literature review, we came across six additional outcomes discussed in the studies that were included in our meta-analysis: age (adult/child), 4,12,25,39,44–46,51,52,55,57,58,61,64,66,69,72 sex (male/female), 4,12,19,39,42–44,46,47,49–51,57–61,64,66,72 smoking status (smoker/nonsmoker), 4,12,25,39,43,44,50,53,56,59,69 injured hand (right/left), 41,46,47,51,52,55,58–60,64,66,72 replant magnitude (incomplete/complete), 4,30,40,41,48,49,58,74 and injured finger (thumb/index/middle/ring/little) 12,39,41,42,45–47,49,51,52,54–56,58,59,61,64,66,72,74 (Table 3). For these outcomes, only smoking status demonstrated a statistically significant difference in replanted digit survival, with smokers having 50% lower odds of survival when compared to patients who did not smoke (Tables 3, 4; OR = 0.50; 95% CI = 0.39 to 0.63; P < 0.001).…”
