More recent meta-analyses might have included some more recently published trials, but their incremental value was uncertain.
This was confirmed by a more recent meta-analysis [63].
Moreover, in more recent meta-analyses positive results favouring NAC are demonstrated only when they include published trials.
A more recent meta-analysis assessed the relationship between migraine and mortality in ten cohort studies, in four of which MA and MwA were investigated separately [96].
A more recent meta-analysis showed a 3.3-fold increase in the same risk in users of combined HCs containing ≥50 μg ethinylestradiol (95% CI 2.5 4.3) [26].
Although a more restrictive CXR strategy seems safe, Ganapathy et al. stated in a more recent meta-analysis that study populations were small and the number of missed findings had not been sufficiently evaluated[33].
A more recent meta-analysis by Henry, MacLeod, Phillips, and Crawford [14] confirmed Birt's [13] findings and made two additional claims.
A more recent meta-analysis of the phenological shifts due to climate change included 125,000 observational series of 542 plant and 19 animal species in 21 European countries[22] which ranged in latitude from 37.35° N to 69.75° [28].
A more recent meta-analysis [31] did not find a sufficient number of pathogen-herbivore studies to analyze separately, but its conclusions (and limitations) for enemy-enemy studies in general were consistent with those of Hatcher [28].
Again, for this important outcome, the more recent meta-analyses [15], [16], [17], [18] suggested that the published evidence demonstrates a statistically significant degree of heterogeneity with I2 statistic ranging from 73% to 85% (Table 2).
