Fig. 2From: Impact of pneumococcal conjugate vaccines on pneumococcal meningitis cases in France between 2001 and 2014: a time series analysisTotal monthly pneumococcal meningitis (PM; grey), ARMAX model predictions (red) and estimated percent changes, 2001–2014. Grey lines are the numbers of expected PM cases during epidemiological periods under the assumption of no change compared to the baseline period (2001–2003). Red lines are the model-estimated PM numbers during epidemiological periods. The percentages indicated above the curves are significant relative changes compared to baseline. NS: nonsignificant. *Stable populationBack to article page
