The phrase "achieved by other methods" is correct and usable in written English.
You can use it when discussing alternative approaches or techniques that can lead to the same outcome as the one being considered.
Example: "The desired results can be achieved by other methods, such as using different software tools or techniques."
Alternatives: "obtained through different means" or "accomplished using alternative techniques."
Meanwhile, as for the studies included but not carried into the meta-analysis, to achieve a qualitative analysis we adopted a method described by others.
We acknowledge that 100 μM concentrations of tocopherols used in cell culture experiments is not an achievable plasma level through oral administration in humans but could be achieved by other methods such as intravenous vitamin E-liposomes [ 24].
The unified equation also results in consistent safety indices for gusset plates, angles, tees, and coped beams with either one or two lines of bolts, a goal that is not achieved by other methods available.
Extension of this technique to a full-bandwidth operation has led to as short as 4.7-fs visible pulses, which is also the first sub-5-fs light source achieved by other methods as the conventional continuum-compression scheme.
And we know that genetic engineering is prohibited in organic farming though the technology can lead to beneficial traits, many of which cannot be achieved by other methods.
Comparison of this method and some of the previously reported preconcentration methods (Table 7) shows that the LOD and preconcentration factor of this method is comparable or better than achieved by other methods described in the literatures.
During the process of museum expansion, SFAP provides a means to document the unfolding architectural drama from a low-height vantage point that would be difficult to achieve by other methods.
The use of SAXS at a modern synchrotron facility allows analysis of a small area (250 × 80 μm), enabling quantification of fibril orientation edge on in relatively thin pericardium tissues, a process that is difficult to achieve by other methods.
We present identification results for two multi-variable systems to show the main features of the proposed method, and to assess its performance against that achieved by other subspace methods.
The comparative results show that the proposed algorithm achieved two new best results for two problem instances, 35 best published results out of 69 instances as achieved by other comparative methods, and comparable results in the remaining instances of INRC2010 dataset.
Unfortunately, this grade of precision cannot be achieved by other imaging methods such as fistulography or computed tomography.
