Relative Risk of Onset of Cancer from the Cholesterol Treatment Trialists’ (CTT) Meta-Analysis of Statin Trials, According to Year of Onset Risk ratios are reported for participants at risk for a first cancer after randomization. Squares with horizontal lines are risk ratios and the corresponding 99% confidence intervals, with the sizes of the squares proportional to the amount of statistical information. The overall risk ratio (diamond) was 1.00 (95% confidence interval, 0.95 to 1.04). The chi-square statistic for trend in the risk ratio for all trials combined was 0.69 (P = 0.40). The data include published data from 13 trials and unpublished data from the 14th trial in the CTT meta-analysis. Peto R et al. N Engl J Med 2008 Sep 2 [Epub ahead of print]

Numbers of Persons with Onset of Fatal or Nonfatal Cancer in the SEAS Trial and in SHARP and IMPROVE-IT Peto R et al. N Engl J Med 2008 Sep 2 [Epub ahead of print]

Relative Risk of Onset of Cancer in the SEAS Trial and in SHARP and IMPROVE-IT, According to Year of Onset Squares with horizontal lines are risk ratios and the corresponding 99% confidence intervals, with the sizes of the squares proportional to the amount of statistical information. The overall risk ratio (diamond) for the SEAS study was 1.55 (95% confidence interval [CI], 1.13 to 2.12) and for SHARP and IMPROVE-IT combined was 0.96 (95% CI, 0.82 to 1.12). The numbers of patients (in either treatment group) with a first cancer recorded during each year (0 to 1, >1 to 2, >2 to 3, and >3) are 201, 194, 115, and 44, respectively, for SHARP and 71, 14, 0, and 0, respectively, for IMPROVE-IT. The chi-square statistic for heterogeneity between risk ratios in SHARP and IMPROVE-IT was 0.01 (P = 0.91). The chi-square statistic for trend over time in the risk ratio for SEAS was 0.00 (P = 1.00), for SHARP and IMPROVE-IT combined was 0.04 (P = 0.84), and for all three trials combined was 0.52 (P = 0.47).

Relative Risk of Onset of Cancer in the SEAS Trial and in SHARP and IMPROVE-IT, According to Recorded Outcome Squares with horizontal lines are risk ratios and the corresponding 99% confidence intervals, with the sizes of the squares proportional to the amount of statistical information; the diamonds indicate the overall risk ratios and 95% confidence interval. The overall risk ratio (diamond) for the SEAS study was 1.55 (95% confidence interval [CI], 1.13 to 2.12) and for SHARP and IMPROVE-IT combined was 0.96 (95% CI, 0.82 to 1.12). The chi-square statistic for the difference between the risk ratios from the SEAS study and from SHARP and IMPROVE-IT combined was 7.5 (P = 0.006). Peto R et al.

Numbers of Deaths from Cancer in the SEAS Trial and in SHARP and IMPROVE-IT Peto R et al. N Engl J Med 2008 Sep 2 [Epub ahead of print]

Relative Risk of Death from Cancer in the SEAS Trial and in SHARP and IMPROVE-IT, According to Year of Onset Squares with horizontal lines are risk ratios and the corresponding 99% confidence intervals, with the sizes of the squares proportional to the amount of statistical information. The overall risk ratio (diamond) for the SEAS study was 1.78 (95% confidence interval [CI], 1.03 to 3.11) and for SHARP and IMPROVE-IT combined was 1.34 (95% CI, 0.98 to 1.84). The chi-square statistic for heterogeneity between risk ratios in SHARP and IMPROVE-IT was 0.53 (P = 0.47). The chi-square statistic for trend in the risk ratio for SEAS was 4.45 (P = 0.03), for SHARP and IMPROVE-IT combined was 1.35 (P = 0.25), and for all three trials combined was 0.38 (P = 0.54). Unlike the 99% confidence intervals in Figure 3, the 95% confidence intervals in this figure do not make any correction for the data-dependent decision to present data on death from cancer separately.
