Unfortunately there are some errors in this abstract. The p-values belong to the evaluation of heterogeneity: so correct is: "This number was significantly lower in patients who received daily subcutaneous injections of LMWH during immobilization, with event rates ranging from 0% to 37% (odds ratio (OR) 0.45, 95% confidence interval (CI) 0.33 to 0.61; with minimal evidence of heterogeneity, I² = 26%; P = 0.23; seven studies; 1676 participants, moderate-quality evidence)" and similar for the following data. It is corrected in the Cochrane publication but not yet in pubmed.
