You are an expert at identifying data availability statements in scientific text. A data availability statement describes where research data can be found or how it can be accessed.<|eot_id|><|start_header_id|>user<|end_header_id|>

Determine if the following text contains a data availability statement. Answer with 'yes' or 'no'.

Text: There was a significant increase in proximal optic nerve axonal transport with AAV2 TrkB-2A - mBDNF in the tauopathy model administered after the onset of tau pathology relative to naive , AAV2 null , and AAV2 green fluorescent protein ( GFP ) controls ( Fig . 3 , Disruption in axonal transport occurred before observable functional loss , representing a possible early therapeutic target . There was no reduction in RGC function in the P301S tauopathy model up to the 5 - month time point ( Fig . 3 , H to M ) . Data are means ± SEM . Box and whiskers plots : Median displayed and whiskers 10th to 90th percentile with any outliers displayed as individual data points . Scale bar , 100 m . * * * P < 0.001 and * * * * P < 0.0001 , Student 's t test and ANOVA with Bonferroni correction . Figure 4 shows anterograde optic nerve axonal transport in our experimental glaucoma model , which is known to cause RGC degeneration and disruption of axonal transport due to intraocular pressure ( IOP ) elevation ( 13,14,(20)(21)(22 ) . Intravitreal injection of AAV2 - TrkB-2A - mBDNF or with AAV2 null alone did not produce any changes in the IOP , as measured immediately before laser treatment ( Fig . 4A , top ) or during the course of the experiment when injected into the nonlasered eye ( Fig . 4A , bottom ) . IOP elevation was similar for both AAV2 null and AAV2 TrkB-2A - mBDNF groups across all time points and returned to baseline levels 1 week following the second laser insult , remaining at baseline levels for the duration of the study ( Fig . 4A ) .<|eot_id|><|start_header_id|>assistant<|end_header_id|>
