Abstract:
The effect of knee-length DVT stockings and structured leg exercises in reducing the risk of deep vein thrombosis (DVT) is of interest. Participants were randomly divided into experimental (n=60) and control (n=60) groups and DVT risk was assessed using the Modified Caprini Risk Score at baseline and Wells Criteria post-intervention. Baseline scores were comparable, confirming group homogeneity, but post-intervention analysis showed a significant reduction in DVT probability in the experimental group. The mean Wells score was 0.82 for the experimental group compared to 5.37 in the control group, with p < 0.001 indicating a highly significant difference. Data shows that simple, non-pharmacological interventions can effectively lower DVT risk in high-risk surgical patients and should be incorporated into routine post-operative care to reduce thromboembolic complications.

Critical Region, Critical Values and Significance Level
In hypothesis testing, a sample statistic is converted to a test statistic using z, t, or chi-square distribution. A critical region is an area under the curve in probability distributions demarcated by the critical value. When the test statistic falls in this region, it suggests that the null hypothesis must be rejected. As this region contains all those values of the...
