Meta-analysis Results:
Figure 1 and Table 4 show the forest plot of the odds ratio of all-cause death compared to Aspirin with placebo in diabetic patients using the Random Effects Model. Figure 1 is statistically significant with a p-value less than 0.05 under the random-effects model with CI varying from 0.63 to 1.17. The confidence intervals slightly crossed the line of no effect showing an insignificant combined result with an average odds ratio of 0.86 for all-cause death among patients taking Aspirin compared to placebo. Figure 2 and Table 5 showed the forest plot of the odds ratio of CVS-related death compared to Aspirin with placebo using Random Effects Model. The result is statistically significant with a p-value less than 0.05 under the random-effects model with CI varying from 0.61 to 1.63. The confidence intervals slightly crossed the line of no effect, showing an insignificant combined result with an average odds ratio of 1.0032 for CVS-related deaths among patients taking Aspirin compared to placebo. Figure 3 and Table 6 show the forest plot and results of the odds ratio for the risk of MI compared to Aspirin with placebo using Random Effects Model. The result is statistically insignificant with a p-value of more than 0.05 under the random-effects model with CI varying from 0.80 to 1.03. The confidence intervals slightly crossed the line of no effect showing an insignificant combined result with an average odds ratio of 0.9106 for MI risk among patients taking Aspirin compared to placebo. Figure 4 and Table 7 show the forest plot and results of the odds ratio for stroke risk compared to Aspirin with placebo in diabetic patients using Random Effects Model. The given figure is statistically insignificant with a p-value more than 0.05 under the random-effects model with CI varying from 0.79 to 1.09. The confidence intervals slightly cross the line of no effect showing an insignificant combined result with an average odds ratio of 0.9328 for stroke risk among patients taking Aspirin compared to placebo. Figure 5 and Table 8 show the forest plot and result of the odds ratio for the risk of bleeding in diabetic patients compared to Aspirin with placebo using the Random Effects Model. The given figure is statistically insignificant with a p-value more than 0.05 under the random-effects model with CI varying from 0.47 to 4.34. The confidence intervals crossing the line of no effect showed an insignificant combined result with an average odds ratio of 1.4411 for bleeding events among diabetic patients taking Aspirin when compared to placebo.
