“…The lowest value for workday missed by parents (PPP$12.70) was reported by Coudeville et al 36 in France, followed by that reported in the Brazilian study (PPP$13.70) 30 . The values reported by other studies varied from PPP$45.60 37 to PPP$326.40 28 .…”

“…Two more articles were added 25,26 from periods studied by previous reviews 2,3 , plus four articles 27,28,29,30 published in 2008.…”

“…40,41 . One study was done in New Zealand 37 , one in Australia 25 , two in Taiwan 44,50 , one in Israel 46 , and one in Brazil 30 .…”
