Risk ratios (RR) were calculated using fixed-effect models.

选用固定效应模型计算rr(相对危险度)。

Where there was significant statistical heterogeneity, we reported risk ratios (RRs) using the random-effects model. For other outcomes we used the fixed-effect model.

在有显著的统计异质性时，使用随机效应模型来呈现相对风险值，其他的预后值则使用固定效应模型。

You do this by zooming to an integer zoom level (an arbitrary fixed-scale experiment to see the effect of different values) and defining a point by latitude and longitude.

实现的方法是缩放到一个整数的缩放级别(可尝试一个任意的固定比例尺以便观看不同值的效果)并通过纬度和经度定义一个点。

With their studios and transmitters in place, broadcasters are, in effect, fixed-cost producers.

The measure would have ensured fixed penalty notices - which had had little effect in curbing shoplifting - could be used only when dealing with first-time offenders.

With that promise in hand, the bank would make the purchase and immediately sell it onto the buyer at a mark-up, agreeing the buyer could pay, say, three months after goods are delivered--in effect, trade finance at a fixed rate with legal protection against default on the one side and loan sharking on the other.
