The phrase 'contribution of study' is correct and usable in written English.
It is often used in academic writing to refer to a piece of research or findings that have contributed to a particular area of knowledge. For example: "This study's contribution to our understanding of the relationship between language and gender is invaluable."
A meta-regression analysis was performed to investigate the contribution of study characteristics to the heterogeneity observed between the case control (n=28) and combined (n=32) studies.
We also conducted independent meta-regressions to estimate the contribution of study characteristics (mean age in years from the age range and year of publication in each study) to heterogeneity among the studies.
These findings highlight the contribution of study settings to inconsistencies in the available literature and can therefore increase the confidence of policy makers when summarizing existing evidence and translating it into policy.
The direct treatment effect estimate in turn drives a network estimate by the value of the corresponding element h t u, d of matrix H. So, the contribution of study s is given by If treatment effect estimate of design d is inconsistent with the treatment effect estimates of the remaining network, the question arises as to how this influences a network estimate.
We adjusted for the contribution of studies with more than one comparison to the overall estimate.
We did not examine the conceptual contribution of studies in this analysis, but we believe this should be explored further.
The results highlight the substantial contribution of studies of species growing outside of the forests to our knowledge of past vegetation and climate dynamics in the Neotropics.
Genome-wide genotyping approaches coupled with sequencing efforts have transformed the landscape of disease genomics and highlight the potentially significant contribution of studies in founder populations.
We would also like to acknowledge the contributions of study collaborators: Tim Aubry, Stephen Hwang, Frances Legault, Vivien Runnels and Jeffrey Turnbull.

We conducted a cumulative meta-analysis of studies ordered chronologically to assess the sequential contributions of studies published over time.
