“…The Anger et al trial used the condom-catheter device and found unclear results (RR 4.38, 95% CI 0.47-41.81), 20 as did both non-randomised studies that assessed purpose-designed UBT (RR 0.49, 95% CI 0.04-5.38 and RR 1.84, 95% CI 0.44-7.69, respectively). 21,23 Regarding the subsequent need for conservative surgical interventions (artery ligation, compressive sutures), the RCT (Anger et al) suggests a statistically significant increase in the risk of additional conservative interventions associated with improvised devices (RR 2.82, 95% CI 1.03-7.71), 20 whereas the non-randomised studies evaluating purpose-designed devices showed unclear results (RR 0.29, 95% CI 0.08-1.06 21,23 and RR 0.21, 95% CI 0.02-1.82 23 ). For other secondary outcomes, the RCT assessing the condom-catheter device found unclear results for maternal deaths (RR 2.23, 95% CI 0.35-14.07), blood transfusion (RR 1.24, 95% CI 0.86-1.80) and transfer to a higher level of care (RR 3.05, 95% CI 0.79-11.70).…”
