The phrase "also showed a weak" is correct and usable in written English.
It can be used when discussing findings or results that indicate a lack of strength or significance in a particular context.
Example: "The study also showed a weak correlation between the two variables, suggesting that other factors may be influencing the results."
Alternatives: "also indicated a slight" or "also revealed a minor".
The analysis also showed a weak negative association between their adaptive capacity and age (r = − 0.026; p ≥ 0.05).
TEM particle size analysis also showed a weak trend with decreasing particle size over time, however, the associated standard deviations were quite big and sometimes overlapping.
However, at these temperatures, the diffractograms of each of the doped catalysts also showed a weak line that is assignable to the magnesium orthovanadate; at 2θ equal to 35.5° (d spacing of 2.52 Å) for BVMgO and at 2θ equal to 23° (d spacing of 3.7 Å) for BaVMgO (Fig. 1a, b, respectively).
In accordance with this performance and his poor stereovision, this subject also showed a weak correlation between incongruence and alternation rates, as well as between incongruence and cortical activation (see below).
NV3Dpol also showed a weak activity of elongation-reaction from a long primer.
They also showed a weak correlation between VPTEF/ VE and airway resistance, reported as percentage predicted [ 6].
We also showed a weaker but significant increase in the odds for having had asthmatic symptoms during the last 12 months with rising levels of NO2.
The intensity of ELF wave radiation also shows a weak correlation with the size of the radiation source or its geographical location.
Similarly, smo-1 mutants also show a weak Muv phenotype (Broday et al., 2004; Leight et al., 2005).
In addition, the samples also show a weak (101) peak, suggestive of the secondary growth direction of the NWs.
The spectra also show a weak luminescence peak at about 1.575 eV, which is identified as the first longitudinal-optical [LO]-phonon replica (designated as A) of the free exciton transition [7].
