The phrase "achieved a regression" is correct and usable in written English.
It can be used in contexts related to statistics, data analysis, or any situation where a decline or reversal in progress is being discussed.
Example: "After implementing the new policy, the team achieved a regression in their performance metrics, indicating a need for further evaluation."
Alternatives: "experienced a decline" or "suffered a setback."
In the absence of more effective therapeutic options, systemic 5-fluorouracil 5-FU -basedd chemotherapy, irinotecan or oxaliplatin is used in order to achieve a regression of the tumour and improved outcome (Ragnhammar et al, 2001; Glimelius, 2003).
When finally convergence was achieved, a PLS regression model calculated on the available experiments allowed to investigate the effect played by each factor on the experimental response.
Administration of anti-PD-1 MAbs (nivolumab and pembrolizumab) in either monotherapy or in combination with anti-CTLA-4 MAbs or traditional chemotherapy has achieved a tumor regression rate of 30%50%% in dealing with melanoma, non-small cell lung cancer, etc. (Larkin et al., 2015).
He achieved a dramatic regression with his first patient using live Streptococcus pyogenes bacteria, the pathogen leading to erysipelas, published in the German Journal 'Berliner Klinische Wochenschrift' (Busch, 1868).
To optimize the process and determine the time and temperature levels at which a desired value of hardness can be achieved, a second-order regression model that captures most of the curvature in the actual relationship between hardness, time, and temperature was developed.
Among the seven machine learning algorithms using a 20-fold cross-validation, two algorithms (SVM and logistic regression) achieved a classification accuracy (CA) >60%, with logistic regression being the best classifier (CA = 62.7%).
Intralesional IL-2 treatment was performed with the aim of achieving a complete regression of all cutaneous and soft-tissue metastases accessible from the skin.
Specifics of the method can be found in Finkelman et al. [ 19], who also examined a nonparametric approach to probability estimation but found that logistic regression achieved a greater reduction in respondent burden.
Coley systematically applied Streptococcus pyogenes extracts – later called 'Coley's toxin' – to cancer patients and achieved a remarkable rate of regressions.
A prediction model based on logistic regressions achieved a very good stratification of the population but had the disadvantages of needing mathematical optimization and being difficult to use in daily clinical practice.
