The phrase "although only a low" is not correct and seems incomplete in written English.
It could be used in a context where you are discussing a low quantity or level of something, but it requires additional information to be clear.
Example: "Although only a low number of participants attended the meeting, we were able to make significant progress."
Alternatives: "despite being a low" or "even though it's only a low".
When the electron-rich substrates were used, more than 95% selectivity for diphenyl disulfide was obtained due to a homocoupling reaction of thiophenol although only a low yield of product was obtained in this case (entries 1, 2, 4, and 5, Figure 4).
Although only a low number of patients were used there was some suggestion of potential prognostic and predictive potential of these signatures.
Although only a low number of patients were included in the mentioned study, patients with neurological morbidity due to bacterial meningitis showed a significantly higher IgG-index in the initial CSF than patients who fully recovered [ 13].
Although only a low to moderate proportion of patients who actually passed away within the observation period were identified by the prediction, the majority of selected patients had corrected predictions, as shown by the NPVs.
However, we did observe higher internal exposure (Schroijen et al. 2007; unpublished results) or more intense biological effects (this paper and also unpublished results on gene expression) near point sources of pollution reaching marginal or even full statistical significance, although only a low number of people were studied around these point sources.
Although only a very low percentage of protein-coding genes are affected by the action of HDAC inhibitors, about 40% of noncoding microRNAs are upregulated or downregulated.
Although we found only a low level of genetic differentiation between subpopulations, the existing differences were characterized by a strong continent-wide correlation between geographic and genetic distance.
Phosphenes are common, although there is only a low passage of ivabradine across the blood retinal and minimal blood brain barrier passage [8], so a small amount of the drug seems to suffice.
In this study, the multiple sequence alignment and the phylogenetic tree (Additional file 1: Figure S1; Fig. 3a, b) illustrated that although there was only a low degree of homology, both of PD-2 and other Rhodobacterales bacteria had conserved regions among AHL synthases.
Although CeMn itself exhibited only a low activity for the direct decomposition of NO into N2 and O2, CeMn modified with alkali or alkaline earth species exhibited significant activities.
Interestingly, although wheat straw contains only a low amount (∼10%) of pectin (Caffall and Mohnen, 2009; Carpita, 1996), a broad range of genes encoding enzymes with pectinolytic activities was expressed only after 24 h exposure to wheat straw.
