Studies on the birth order of patients with multiple sclerosis have yielded contradictory conclusions. Most of the sets of data, however, have been tested by biased tests. Data that have been submitted to unbiased tests seem to suggest that cases are more likely to occur in early birth ranks. This should be tested on further samples and some comments are offered on how this should be done.
关于多发性硬化症患者出生顺序的研究得出了相互矛盾的结论。然而,大多数数据集都经过了有偏差的测试。经过无偏差测试的数据似乎表明,病例更有可能出现在较早的出生顺序中。这一点应在更多样本上进行验证,并就如何进行验证给出了一些建议。
