Percent sensitivity (95% Confidence Intervals) of CRP at thresholds of 10, 20 and 40 mg/L by etiological group among febrile inpatients and outpatients, Kilimanjaro Christian Medical Centre and Mawenzi Regional Referral Hospital, Tanzania, 2011–2014. For each etiologic grouping, the number of febrile inpatients and outpatients exceeding the respective CRP threshold is shown as a numerator and the denominator shows the total number of febrile participants who met criteria for the etiologic grouping.
