Figure 3. Forest Plot of the Changes of Severity of Tinnitus.
When the effect size is less than zero, it indicated the specified treatment was associated with higher improvement in severity of tinnitus than controls. a-tDCS indicates anodal transcranial direct current stimulation; cTBS, continuous theta-burst stimulation; c-tDCS, cathodal tDCS; dTMS, deep transcranial magnetic stimulation; F3, over the left dorsolateral prefrontal cortex (DLPFC); F4, over the right DLPFC; F3F4, over the bilateral DLPFC; Fp2, over the right supraorbital area; HF, high-frequency; iTBS, intermittent TBS; LF, low-frequency; rTMS, repetitive TMS; SMD, standardized mean difference; T3, over the left auditory cortex; T4, over the right auditory cortex; T3T4, over the bilateral auditory cortices; and tRNS, transcranial random noise stimulation.
