Reversible Audiometric Threshold Changes in Children with Uncomplicated Malaria
Figure 1
(a) Audiometry data on 80 patients with uncomplicated malaria before treatment (shaded) and 57 healthy controls (open). Box plots show mean, quartiles, 95% and 5% percentiles, and outliers. Data for right ear have been shown in all figures; measurements on the left ear gave essentially identical results throughout. Hearing thresholds were significantly higher in patients than in controls across all wavelengths (two-way repeated measurement ANOVA on ranks , post hoc test significant () for all wavelengths). (b) Audiometry data on 58 patients followed up 9–12 months after an attack of uncomplicated malaria (shaded) and 57 healthy controls (open, same as in (a)). Hearing thresholds were significantly lower in recovered patients than controls across all wavelengths and both ears (two-way repeated measurement ANOVA on ranks , median difference <5 dB).
