| pubmed-article:2802808 | pubmed:abstractText | The mean Hackett score is a commonly used index in malaria surveys. It is, however not suitable for comparing the distribution of hypertrophied spleens among small population samples, owing to the validity conditions of statistical tests. The authors suggest to use another index, the median Hackett score, which can be compared to the Tukey test. This test gives a graphical representation of hypertrophied spleen distribution, allowing for rapid and easy comparison. The lack of power of this test is compensated by its robustness (a consequence of its broad limits of validity), its graphical simplicity and its easy interpretation. | lld:pubmed |
