The phrase "a previous study established" is correct and usable in written English.
You can use it when referring to findings or conclusions drawn from an earlier research study in academic or scientific writing.
Example: "A previous study established a significant correlation between sleep quality and academic performance."
Alternatives: "an earlier study demonstrated" or "a prior study indicated".
Our results are consistent with previous findings of increased p53 mutational frequency in H. pylori-associated gastric cancer cases (Shibata et al., 2002) and corroborate a previous study establishing CagA as a bona-fide oncoprotein (Ohnishi et al., 2008).
Our previous study established a model simulating insufficient RFA in vitro and showed that insufficient RFA could directly promote the invasiveness and metastasis of HCC cells and the EMT of HCC cells through Akt and ERK signaling pathways [ 11].
Additionally, the previous study established an association between the evolutionary rate of genes and the breadth of expression, i.e. the number of tissues in which a gene is expressed.
Previous studies established a role for SR-A in integrin-independent adhesion of macrophages to an uncharacterised serum ligand (16).
Given that previous studies established a good safety profile it was not a requirement that patients were medically refractory per established criteria [6], however, most had tried several or all pharmaceutical options and were considered difficult to treat with a high headache burden.
Previous studies established a strong association between anti-RR and IFN/RBV therapy [10, 11, 12, 14, 15], such that we previously described anti-RR as a drug-induced autoantibody [13].
Salinity tolerance is a complex quantitative trait and previous studies established its strong association with visual symptoms (as indicated by the SES score) and other traits such as shoot length, root length, shoot fresh weight, and shoot dry weight.
However, two previous studies established a role of CD146 in vascular development in zebrafish, by demonstrating that the suppression of CD146 affected vascular lumen formation of intersomitic vessels (Chan et al., 2005), and also angiogenic sprouting of intersegmental vessels (So et al., 2010), which is in apparent contradiction with our mouse studies.
Previous studies established a strong association between limb neuromuscular involvement and duration of mechanical ventilation.
