2. Figure 1
Proportional effects of unfractionated heparin (UFH) and low-molecular weight heparin (LMWH) on heparin-associated thrombocytopenia in medical and surgical patients who received prophylaxis. Summary and individual study results are shown. All studies were prospective with >100 patients in each arm. Black squares = point estimates (with area proportional to number of events) and horizontal lines = 95% confidence interval (CI) for observed effects in different subgroups. Diamonds = point estimate and 95% CI for overall effects, with proportional reductions indicated alongside. Solid vertical line = hazard ratio of 1.0 (ie, no effect of treatment), and dotted vertical line = observed overall effect. DVT = deep venous thrombosis; VTE = venous thromboembolism; surg = surgical; med = medical; gyn = gynecological.

4. Figure 3
Proportional effects of unfractionated heparin (UFH) and low-molecular weight heparin (LMWH) on heparin-associated thrombocytopenia in patients who received either treatment or prophylaxis. Black squares = point estimates (with area proportional to number of events) and horizontal lines = 95% confidence interval (CI) for observed effects in different subgroups. Diamonds = point estimate and 95% CI for overall effects, with proportional reductions indicated alongside. Solid vertical line = hazard ratio of 1.0 (ie, no effect of treatment), and dotted vertical line = observed overall effect. DVT = deep venous thrombosis; VTE = venous thromboembolism; PE = pulmonary embolism; surg = surgical; med = medical; gyn = gynecological.
