Figure 4: (a) Allowed region of the neutrino oscillation parameter from KamLAND antineutrino data (colored regions) and solar neutrino experiments (lines) [30]. (b) the result of a combined two-neutrino oscillation analysis of KamLAND and the observed solar neutrino fluxes under the assumption of CPT invariance. Taken from [39].
