The phrase "a preceding study" is correct and usable in written English.
It can be used when referring to a study that was conducted before the current one being discussed or analyzed.
Example: "The results of our research build upon the findings of a preceding study that examined similar variables."
Alternatives: "an earlier study" or "a prior study".
In a preceding study, indocyanine green (ICG) angiography was positively tested for detecting early stage flap malperfusion.
First, a non-linear variant of the Principal Component Analysis (Isomap) was performed in a preceding study to identify prevailing biogeochemical processes controlling water chemistry.
To tackle this problem and to complement a preceding study (Brandt et al., 2016), we introduce here an advanced approach that integrates compound-specific δ13C isotopes (CSSI) and fallout radionuclides (FRN), Excess lead-210 (210Pbex) and Cesium-137 (137Cs) to estimate past net erosion rates of dominant land use types in the mountainous catchment Chieng Khoi (207 ha, Northwest Vietnam).
Therefore, the output of a preceding study supported us in defining the scope of the following study in more detail.
In other words, guidelines are complementary and support each other (e.g., results from a preceding study can be used to corroborate or further develop other results).
A culture isolated from ascospores of Hypoxylon rickii, a xylariaceous ascomycete collected in Martinique, had yielded botryane, noreremophilane and abietane-type terpenoids in a preceding study, but additional metabolites were detected by extensive HPLC MS analysis in other fractions.
This study also further excluded patients who had suffered an AECOPD in the year preceding study recruitment, which is a strong predictor for subsequent AECOPD and considered an indicator for the frequent exacerbator phenotype [ 14].
The work is a major extension of our preceding study (21) considering the amount of simulations (775 ns) and the number of studied structures.
The effects of such engineering parameters on biological cultures have been addressed in only a few preceding studies.
It is a continuation of the preceding studies of a single-notch diffraction focused on the manifestation of the trapped mode and resonance transmission effects in the case of several obstacles.
A number of preceding studies have measured WTP for medical services for such purposes [ 6, 7].
