Example sentences for: nnh
How can you use “nnh” in a sentence? Here are some example sentences to help you improve your vocabulary:
7 per thousand among unexposed (77 cases among 2222 unexposed) for a NNH of 16.
Relative benefit or risk was considered to be statistically significant when the 95% confidence interval did not include 1. NNT or NNH values were only calculated when the relative risk or benefit was statistically significant, and are reported with the 95% confidence interval.
Importantly, estimates of NNH as calculated by differences between exposed and unexposed prevalence rates, shown above, were very similar to NNH determined using differences between our estimated 9-month incidence rates in exposed and unexposed (NNH was 17 for AR and 108 for MR by this approach), further illustrating the internal consistency of our analysis.
Relative benefit and relative risk estimates were calculated with 95% confidence intervals using a fixed effects model [ 19 ] . Heterogeneity tests were not used as they have previously been shown to be unhelpful [ 20 21 ] , though homogeneity was examined visually [ 22 ] . Publication bias was not assessed using funnel plots as these tests have been shown to be unhelpful [ 23 24 ] . The number needed to treat or harm (NNT and NNH) with confidence intervals was calculated by the method of Cook and Sackett [ 25 ] from the sum of all events and patients for treatment and placebo.
NNH may be calculated as the inverse of the difference between risk in exposed and risk in unexposed persons.
