Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? Radiographers with a CT-specific qualification were more likely to achieve a high knowledge score than those without (58.3% vs. 55.7%), but the association was not statistically significant (OR 1.11, 95% CI 0.70–1.76; p = 0.72). → Hadi Yasser H. 2026
q2 i? Weekly workload showed no meaningful association with knowledge (58.3% vs. 55.1%; OR 1.14, 95% CI 0.71–1.84; p = 0.63), and experience showed a similarly nonsignificant difference (OR 1.18, p = 0.50). → Hadi Yasser H. 2026 (2)

q2 · i? · associational · r2
Unadjusted odds ratios with Fisher's exact test on a composite knowledge score (0–8) dichotomised at the median (≥5 = high knowledge) for 321 radiographers; the qualification association did not reach statistical significance.
"Radiographers with a CT‐specific qualification were more likely to achieve a high knowledge score than those without (58.3% vs. 55.7%; OR 1.11, 95% CI 0.70–1.76; p = 0.72)."

q2 · i? · associational · r1
Secondary analysis of knowledge-score associations; experience (>10 years vs. ≤10 years) also showed a nonsignificant difference (59.5% vs. 55.4%; OR 1.18, 95% CI 0.76–1.84; p = 0.50).
"Weekly CT workload showed no meaningful association with knowledge: respondents performing ≥ 60 scans per week and those performing fewer had nearly identical rates of high knowledge (58.3% vs. 55.1%; OR 1.14, 95% CI 0.71–1.84; p = 0.63)."
Discussion¶
Related Claims¶
- Routine post-acquisition verification of HU values is uncommon and knowledge of positioning effects on CT numbers is inconsistent — related
- Access to and consistent use of automated centring technology remain limited among CT radiographers — related
- Radiographers show substantial uncertainty about how localiser radiograph direction affects radiation dose and ATCM behaviour — related
- Mean CT centring knowledge score indicates only moderate proficiency, with greater score variability among less experienced and lower-volume radiographers — reports the opposite
- Vertical off-centring below the gantry isocentre is the most frequently reported CT positioning error among radiographers — related
