Test of photopic negative response of electroretinogram with DTL electrode in normal Chinese subjects
Bibliographic record
Abstract
ObjectiveTo test normal values of photopic negative response (PhNR) of electroretinogram (ERG) with DTL electrode in normal Chinese subjects and to evaluate the characteristic of PhNR.MethodsERGs were recorded on 65 normal subjects (112 eyes) aged 21-76 years using disposable DTL electrodes at full-field ganzfeld brief red flashes on a blue background (luminance of 10 cd/m 2 ).Stimulus flashes of different intensity (1cd·s/m 2 ,5cd·s/m 2 and 7cd·s/m 2 ) were generated by light emitting diodes (LEDs).The amplitudes and latencies of PhNR with age were analyzed.ResultsThe data were divided into 50 years group and ≥50 years group after statistical analysis.The mean latencies in the 50 years group was 65.83±4.06ms,66.17±6.48ms and 65.81±6.71ms at 1,5 and 7 cd·s/m2 respectively which was statistically significant different from that ≥50 years group(69.86±5.68ms,71.33 ± 4.90ms and 70.40±4.61ms,respectively)(P0.001).Mean amplitude of 50 years group was significantly higher than that of ≥50 years group at different stimulus intensities ( -38.94 ± 10.21μV,-38.51± 10.97μV,-38.62± 9.98μV vs-32.41± 7.76μV,-34.52±8.90μV,-33.96± 9.81μV,respectively)(P0.001,P=0.047,P=0.017).ConclusionUse of disposable DTL electrodes can prevent cross infection.Our results record the normal values of PhNR by age group in normal Chinese subjects and provide normal reference limits in clinical practice.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
