Multivariate survival analyses: sensitivity analysis of adjusted hazard ratios for previously undiagnosed diabetes. This figure presents the results of four sets of three multivariate survival analyses, which evaluate the sensitivity of the baseline findings reported in Table 3 (upper right quadrant in Figure) based on the inclusion and exclusion of cancer stage at diagnosis and measures of prior health system contact. Within each quadrant are the results of 3 separate multivariate analyses, one for each mortality outcome. Triangles represent the adjusted hazard ratios for previously undiagnosed diabetes (compared to previously diagnosed diabetes). Ticks represent the upper and lower bounds of the 95% confidence interval corresponding to the hazard ratio. Confidence intervals that do not overlap 1.0 are statistically significant at a threshold of P = 0.05.
