Sentence examples for cases expected number from inspiring English sources

Based on a predicted sample size of 150 170 cases (expected number of cases based on STEC cases notified nationally in two preceding years) and an attempted case to control ratio of 1 3, there was sufficient statistical power (at least 80%) at a confidence level of 95% to detect an odds ratio of 3.0, using 5%, 20% and 80% as the expected frequencies of exposure among controls.

*Obs, observed number of cases; Exp, expected number of cases; SIR, standardized incidence ratio; CI, confidence interval; EHEC, enterohemorrhagic Escherichia coli.; TTP, thrombotic thrombocytopenic purpura.

*Obs, observed number of cases; Exp, expected number of cases; SIR, standardized incidence ratio; CI, confidence interval; EHEC, enterohemorrhagic Escherichia coli.

The likelihood ratio statistic is given by (1) max i L i L 0 = C i E i C i N - C i N - E i N - C i I (C i > E i ), where the observed number of cases and expected number of cases inside a circle are denoted by C i and E i, respectively and the observed number and expected number of cases outside a circle are denoted by (N -  C i ) and (N- E i ), respectively.

The geographic cluster analysis did not identify any places in New Jersey where the relative risk of ALS (observed number of cases vs. expected number of cases) was statistically significantly high; however, the smoothed relative risk maps did identify distinct regional differences in ALS risk throughout the state.

In the remaining eight cases, the expected number is lower than the observed number (see Additional File 1).

We then calculated the standardised incidence ratio as the ratio between the observed number of cases and the expected number of cases.

A foodborne outbreak is defined in European legislation as "an incidence, observed under given circumstances, of two of more human cases of the same disease and/or infection, or a situation in which the observed number of human cases exceeds the expected number and where the cases are linked, or are probably linked, to the same source" [ 25].

The SMR is defined as the ratio of observed cases and the expected number of deaths.

We calculated the standardized incidence ratio (SIR) by dividing the observed number of SPM cases by the expected number based on the general population rates.

We then compared the observed number of cases to the expected number and calculated a 95% CI, assuming that the observed number of cancers in a specific category followed a Poisson distribution.
