Conventional endotracheal tubes versus polymer-coated tubes in ventilator-associated pneumonia development: A systematic review and meta-analysis.

Although the difference in mortality between the two groups did not reach statistical significance (p = 0.59), it is worth noting that the point estimate of the RR suggests a slight increase in mortality among patients using conventional tubes: Risk Ratio (RR 1.04 Cl 95 % 0.89–1.22; p = 0.59; I 2 13 %) ( Fig. 6 ).

The relative risk (RR) was calculated at −0.99, suggesting a slight trend toward reduced length of stay compared to those who did not use these tubes.

Thus, while the results indicate a favorable trend, the absence of statistical significance, coupled with high heterogeneity, underscores the need for further investigations that can elucidate the real impact of silver tubes on clinical outcomes.
