Cross-Over REPACK

Background: Meta-analysis of randomized controlled trials (RCTs) is usually based on trials where patients are randomized individually into two different, parallel, treatment groups. This paper concentrates on RCTs of a different design-two-period, two-treatment cross-over trials.


Results: Methods are described for continuous and binary data for use both when the necessary paired data are given and also when they need to be calculated or imputed, and some suggestions are provided to help people wishing to synthesize data from cross-over trials into meta-analyses. The survey suggested that about 8% of the trials in the Cochrane library were cross-over trials and 18% of the reviews referred to such trials, although there was no consistent approach to their inclusion into the reviews.

Conclusions: Methods do exist for including valuable information from two-period, two-treatment cross-over trials into quantitative reviews. However, poor reporting of cross-over trials will often impede attempts to perform a meta-analysis using the available methods.

The cable cross-over is an isolation movement that uses a cable stack to build bigger and stronger pectoral muscles. Since it's done using adjustable pulleys, you can target different parts of your chest by setting the pulleys at different levels. It is common in upper body and chest-focused muscle-building workouts, often as a pre-exhaust at the beginning of a workout, or a finishing movement at the end. It is often in combination with other presses or flyes to target the chest from different angles. 041b061a72
