  1. Data are based on a systematic review of 88 records of field samplings retrieved from 48 articles published between 1964 and 2016. Data are sorted for bednet presence in sampled villages. Cochran’s Q test assesses whether the proportion of observed studies is consistent. Inconsistency test (I2) describes the percentage of total variation across studies that is due to heterogeneity rather than chance. *P = 0.0005. **P < 0.0001.
