The phrase "a previous study explained" is correct and usable in written English.
You can use it when referring to findings or conclusions from an earlier research work in a discussion or analysis.
Example: "A previous study explained the correlation between sleep patterns and cognitive performance, providing valuable insights for our current research."
Alternatives: "an earlier study described" or "a prior study detailed".
Three among them were mentioned in a previous study explaining co-operatively working modes of the two pathways.
In contrast, previous study explains that there is a relationship between antibacterial activity and cell wall composition (Khoufi et al. 2008; Yangui et al. 2008).
Previous studies explain this behaviour as a result of the difference in activation of the musculature involved, indicating that women, with a reduced knee flexion, perform the jumping action mainly by calling on the quadriceps, whereas men perform this movement with a more intense activation of the quadriceps and isquiotibiales [ 2, 6, 8, 26].
The TPB has been used to explain intention to promote physical activity and offer smoking cessation intervention in two previous studies, explaining 61% and 40% of the variance respectively [ 9, 33].

20 23 In a previous study, cognitive dysfunction explained the association between increasing age and poorer performance on the TOFHLA and NVS among older adults, while performance on the REALM was best among the oldest adults who screened negative for cognitive dysfunction.

In a previous study this was partly explained by their level of knowledge [ 18].
The variations of the EWF fracture parameters with T are consistent with those of a previous study in LDPE, and are explained in terms of molecular relaxation, ethylene phase content, and changes in the yield and fracture stresses.
