The phrase "adjustments have only" is correct and usable in written English.
It can be used when discussing the limitations or specific conditions under which adjustments are made or applicable.
Example: "In this study, we found that adjustments have only been effective in certain scenarios."
Alternatives: "adjustments are limited to" or "adjustments apply solely to".
As these adjustments had only marginal influence on observed associations, adjusted models only were reported in tables.
Since these adjustments had only minor effects on the associations and significance levels obtained without adjustment (i.e. we never observed significance in the unadjusted data that was not also present after adjustment; data not shown), stepwise and interaction analyses were performed without adjusting for these parameters.
These adjustments had only modest effects.
Temperature adjustments had only a small impact and RT was selected to minimise the necessary equipment.
Overall, a 10-percentage unit decrease in silage DM over short-term bouts (with or without total mixed ration adjustment) had only minor effects on DMI, milk yield, and composition.
The adjustment had only a small impact.
3 However, the additional adjustment had only a minor impact on the results (data not shown) and did not alter our conclusions.
BMI adjustment had only minor effects on the outcomes except for a loss of significance of cold detection threshold and VPT.
To minimise the potential for such confounding, we adjusted for risk factors at baseline which were identified as carrying an adverse prognosis independent of surgical treatment, and reassuringly, this adjustment had only minor impact on the risk estimates of main interest.
Mutual adjustment had only a minor impact on the other three criteria's association with mortality, with the lowest adjusted ORs found for assessment of ADL before discharge (OR 0.21, 95% CI 0.15 to 0.30) and prevention of future osteoporotic fractures (OR 0.57, 95% CI 0.38 to 0.85).
