We present new results of measurements of reactor antineutrino flux andspectrum dependence on the distance in the range 6-12 meters from the center ofthe reactor core at SM-3 reactor (Dimitrovgrad, Russia). Additionalmeasurements were carried out and set of data to perform statistical analysiswas almost doubled since the previous report. Using all collected data weperformed the model independent analysis on the oscillation parameters $\Deltam^2_{14}$ and $\sin^2(2\theta_{14})$. The method of coherent summation ofresults of measurements allows us to directly observe the effect ofoscillations. We observed an oscillation effect in vicinity of $\Delta m^2_{14}= (7.25\pm0.13_{st}\pm1.08_{sys}) \text{eV}^2$ and $\sin^2(2\theta_{14})=0.26\pm0.08_{st}\pm 0.05_{sys}$. We provide a comparison of our results withresults of other experiments on search for sterile neutrino. Combining theresult of the Neutrino-4 and the results of measurements of the gallium anomalyand reactor anomaly we obtained value $\sin^2(2\theta_{14})\approx0.19\pm0.04(4.6\sigma)$. Also was performed comparison of Neutrino-4experimental results with results of other reactor experiments NEOS, DANSS,STEREO, PROSPECT and accelerator experiments MiniBooNE, LSND and the IceCubeexperiment also. Sterile neutrino mass which can be calculated using theNeutrino-4 data in assumption that $m^2_4 \approx \Delta m^2_{14}$ is $m_4 =(2.68 \pm 0.13)\text{eV}$. Considering estimations of mixing angles obtained inother experiments we can calculate masses of electron neutrino, muon neutrinoand tau neutrino: $m^{\text{eff}}_{\nu_e} = (0.58 \pm 0.09)\text{eV},m^{\text{eff}}_{\nu_{\mu}} = (0.42 \pm 0.24)\text{eV},m^{\text{eff}}_{\nu_{\tau}} \leq 0.65\text{eV}$. Extended PMNS matrix for (3 +1) model with one sterile neutrino is provided, neutrino flavor mixing schemewith sterile neutrino and global fit of reactor experiments.
