This was based on the fact that, if they are successful, second generation techniques (generally speaking) perform better, are less invasive, and have fewer adverse events.
Ethanol production in Brazil is exclusively developed by first generation techniques, through saccharose fermentation, however, if other vegetable parts from sugarcane could be used for this application, the country would improve its biofuel efficiency and reduce the land area for plant cultivation (Gray et al. 2006).
Dissatisfaction levels with second generation techniques were slightly lower than those associated with first generation techniques.
Six of these studies involved first generation techniques.
18 Thus they are clearly preferable to first generation techniques.
Our previous review indicated that levels of dissatisfaction with second generation techniques, as a class of procedure, were slightly lower than those associated with first generation techniques.
We found that second generation techniques, such as thermal balloon ablation (Thermachoice and Cavaterm), 46 67 68 the Novasure device, 48 or microwave (Microsulis), 51 69 were at least as effective as first generation techniques.
14 For second generation techniques, we used complication rates with microwave endometrial ablation as a proxy 15 because the complication rates from MISTLETOE for the second generation techniques refer to slightly outdated procedures and are no longer relevant.
Second generation techniques are typically non-hysteroscopic, vision control is not required, and they tend to be easier to perform.
Although first generation ablation might sound like an approach that has been superseded by second generation ablative techniques, outcomes from first generation techniques are still acceptable, and the technique is sometimes considered more versatile than some second generation approaches.
41 Fourteen studies compared first generation endometrial destruction techniques with second generation techniques, 19 44454647484950515253549 50 51 52 53 54 and eight studies compared Mirena with endometrial destruction, three of which were first generation 20 55 56 and five second generation.
