    “…Images of patients acquired using ACS and conventional acceleration methods were compared in terms of acquisition times, signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR), subjective image quality, and diagnostic agreement. Shapiro-Wilk test, Cohen κ, intraclass correlation coefficient, and one-way ANOVA with post hoc tests (Tukey or Dunn) were used. …”

    “…Simple effects tests followed by comparisons with Bonferroni corrections were used, and effect size calculations were performed using Cohen’s f statistic. RESULTS: Tracking accuracy on the MOT task was significantly affected by sports expertise (F((1,124)) = 91.732, p < 0.001, η(P)(2) = 0.425), with accuracy among expert soccer athletes superior to that among novice soccer athletes. …”

    “…Anticipation of pN stage was best achieved with subjective US findings and the smallest diameter (Cohen’s κ = 0.713 and 0.438, respectively). CONCLUSION: Our LN mapping and meticulous 1:1 node-by-node comparison reveals the usefulness of US for detecting metastatic involvement of neck LNs in head and neck carcinomas as compared to histopathology. …”

    “…Estrone and estriol content of rabbit urine extracts can be determined by the concentration of the colored compound they form upon diazotization with sulfanilic acid and by the modified phenolsulfonic acid test of Cohen and Marrian. Estriol can be determined by the specific reaction first described by David. …”

    “…RESULTS: Clinically significant improvements were realized post-intervention and at 6-month follow-up for outcomes related to diabetes and depression. Effect sizes using Cohen's d were determined post-intervention and at 6-month follow-up, respectively, for HbA1c (d=0.36; d=0.28), PHQ-9 (d=1.48; d=1.67, and PAID (d=1.50; d=1.06) scores. …”

    “…Patients with active disease achieving remission at follow-up yielded greater reductions of ultrasound inflammatory scores than those with stable clinical activity (Cohen’s d effect size ranging from 0 to 0.79). Inter-rater reliability of bi- and unilateral composite scores was moderate to good with ICCs ranging from 0.42 to 0.96 and from 0.36 to 0.71, respectively for inflammatory and structural sub-scores. …”
