Continuity-based RD analysis: effect of redlining on the mean BMI in third-generation adults using covariate-adjusted local polynomial regression

N = 210	RD estimator (kg/m2)	MSE-optimal bandwidth [meters]	Robust inference				Nl	Nr
			95% CIrbc	SE	p-value	CER-optimal bandwidth [meters]
Outcome: Body Mass Index (mean)
Model 1b	5.16	290.89	[− 2.54, 9.81]	3.15	0.249	239.21	11	69
Model 2b	5.37	314.26	[− 2.29, 10.73]	3.32	0.204	258.43	11	69
Model 3b	5.92	405.77	[− 2.08, 13.86]	4.07	0.148	333.68	13	86
Model 4b	7.46	374.44	[− 4.00, 16.60]	5.26	0.231	308.87	10	78

Discrete analysis using cluster standard errors; bandwidth is the distance (in meters) from yellow/red border to grandparent’s census block; adjusted models: 2b — age, year; 3b — age, year, gender; 4b — age, year, gender, race; all models use a first-degree polynomial; Nl (left) and Nr (right) indicate the effective number of observations within the MSE bandwidth used for estimation
