Table 3. Peak-to-trough ratios (95% confidence intervals) of summarized monthly deaths during 1977–2016 (within 90 days following deep vein thrombosis, pulmonary embolism, provoked VTE, unprovoked VTE, and splanchnic vein thrombosis) and during 1994–2016 (within 90 days following cerebral vein thrombosis and retinal vein thrombosis).
