“…A related limitation of this dataset was that its large size may have increased the possibility of finding statistically-significant effect sizes. Though the effect sizes were consistent with or larger than prior studies that also used non-experimental data to evaluate center-based care (e.g., Bassok, 2010;Claessens, 2012;Loeb et al, 2007;Turney & Kao, 2009;Yamauchi & Leigh, 2011), they were nonetheless smaller than those derived from experimental work on center-based care (e.g., Yoshikawa et al, 2013). Again, this urges for future experimental work to consider chronic absenteeism as an outcome in order to compare to the findings in this study.…”
