The analysis restricted to the 40-kb sfl locus reduces the burden of multiple testing by several orders of magnitude, but also fails to identify a significant association.
The analysis restricted to the studies reporting cases among HCWs, regardless of their specific professional role, did not show any significant variation of the IRR estimates.
The analysis restricted to eight studies (excluding the studies by White, Odone-Filho and Moll, with different designs) indicates 36.22 expected cases of childhood cancer and 35 observed, giving a SIR of 0.97 (95% CI 0.69 1.10).
The analysis restricted to nurses, nurse assistants and non-medical staff identified the same determinants.
The analysis restricted to children < 15 years of age showed a multivariate RR of 0.78 (95% CI, 0.61 1.01).
The analysis restricted to studies that reported both RRs adjusted and not adjusted for BMI showed similar differences in SRRs (Table 2).
The analysis restricted to a generalist primary care professional group (combined GPs and adult nurses) may in part address this limitation.
The analysis restricted to physicians showed that working in a private nursing home and the provision of training sessions or staff meetings (RR: 1.13, 95% CI: 1.0 - 1.28, p = 0.05) increased vaccination rates.
The analysis restricted to high quality trials (see web extra) could be carried out only for all strokes (0.81, 0.57 to 1.17) and for congestive heart failure (1.47, 1.19 to 1.83).
The background is subtracted, the analysis restricted to the 0.1 to 6 keV range, a model is created - consisting of an absorbed power law - and then parameter values are set before the fit is made.
In addition, we found similar results in the analysis restricted to adenocarcinoma cases only: TGGCACTC (p-value = 0.008) and CGGCGCCT (p-value = 0.023).
