The utility of the roll-over test (ROT) as a prognostic tool for predicting pregnancy-induced hypertension (PIH) was examined in primiparas in Quito, Ecuador. In Study I, 14 of 16 subjects with a +ROT developed PIH (positive predictive value (PPV) = 88%); only 2 of 27 subjects with a -ROT developed PIH (negative predictive value (NPV) = 92.5%). In Study II (n = 66), the PPV and NPV were 71.4% and 78.6%, respectively. Data from these and previous studies indicate that although the ROT is not a perfect predictor, its advantages recommend usage in populations with high PIH-associated maternal and perinatal mortality.
在厄瓜多尔基多的初产妇中，对翻身试验（ROT）作为预测妊娠高血压（PIH）的预后工具的效用进行了研究。在研究I中，16名翻身试验阳性（+ROT）的受试者中有14名发生了PIH（阳性预测值（PPV）=88%）；27名翻身试验阴性（-ROT）的受试者中只有2名发生了PIH（阴性预测值（NPV）=92.5%）。在研究II（n=66）中，PPV和NPV分别为71.4%和78.6%。这些研究以及之前研究的数据表明，虽然翻身试验并非完美的预测指标，但其优势使其推荐用于PIH相关孕产妇和围产儿死亡率较高的人群。
