Length of hospital stay. In this
particular outcome, we pooled the findings of four RCTs (39) (40) (41)
(42), delivering an MD 10.73 (95% CI -2.28 to 23.74) with a high level
of heterogeneity (I²= 65%), shown in Figure 7 (Forest plot of
comparison: Paraffin oil versus standard therapy, outcome: 1.2 Length of
hospital stay). The sensitivity analysis with additional adjustments
following other summary statistics, delivering an SMD of 0.51 (95% CI
0.02 to 1.01; I2=70%. Removing trials classified as
high risk of bias from the analysis (40) (41) yielded an MD of 22.41
(95% CI: -15.35 to 60.18) while maintaining a high level of
heterogeneity (I2 =
82%).
