q3 i? The intention-to-treat effect for pupils with a zero vulnerability score was -0.012 (95% CI [-0.103, 0.080]), not statistically significant, though estimates were sensitive to including controls. → Sandra McNally 2014

q3 · i? · causal · r2

Intention-to-treat regression for 1124 non-vulnerable pupils (Table 6b: effect size -0.012, SE 0.044, 95% CI [-0.103, 0.080]), not significant. The report notes that with additional controls the point estimate became "negative and significant at the 5 per cent level" at -0.06 standard deviations.

"In the case of other (non -vulnerable) pupils, estimates are sensitive to including controls, with the point estimate becoming negative and significant at the 5 per cent level (although small in magnitude at -0.06 standard deviations)."
