  3. Table 1 shows that after adjusting for other covariates, our logit models indicate that an average one unit increase of VHWs per health center is associated with a decrease in hospital/clinic admission for diarrhea (OR 0.9885, 97.5%CI 0.9879, 0.9890), dysentery (OR 0.9807, 97.5%CI 0.9790, 0.9824), wound care (OR 0.9848, 97.5%CI 0.9843, 0.9853), depression/anxiety (OR 0.9637, 97.5%CI 0.9615, 0.9660), dental caries (OR 0.9704, 97.5%CI 0.9699, 0.9708), and skin infection (OR 0.9909, 97.5%CI 0.9905, 0.9914), while a non-significant increase was observed for scabies (OR 0.9998, 97.5%CI 0.9985, 10,011) and conjunctivitis (OR 0.9997, 97.5%CI 0.9989, 1.0005). For model fit, Table 1 details key fit descriptors by reporting the McFadden’s Pseudo-R2 and deviance statistics for each of the models. The deviance statistics were all significant, thereby indicating that our models were superior to their null (intercept-only) counterparts. Lastly, the high McFadden’s Pseudo-R2 values also indicates that the model is well fit. The level of signifcane for each of the deviance tests is reflected by * p < 0.05, ** p < 0.01, *** p < 0.001
