Abstract
The purpose of this project is to develop a sample size framework for investigating differences between insecticide treatments in WHO Tube assays, with a particular focus on PBO synergism. While typically sample sizes are determined prior to a study to reliably detect a given effect size, current WHO guidance fixes the sample size of this synergism assay to four tubes of each treatment (‘4x4’). This pre-determined sample size limits the effect size that can be reliably detected. Consequently, experimental setups may not be powered to detect smaller differences in mortality between treatments and is at risk of exaggerating the magnitude of comparisons that are found to be significant (the lesser known risk of underpowered studies). A better understanding of the power of this 4x4 setup to detect differences between treatments is needed. General rules-of-thumb are required for what effect sizes can be reliably interpreted as a true effect, ideally in the form of a ‘threshold’ where only a mortality difference larger than a pre-defined amount is considered indicative of synergism. Additionally, while it would be ideal if all bioassays were conducted simultaneously on the same day, in practice assays may be spread over multiple days thus introducing a between-day variation which must be accounted when assessing power and setting appropriate synergism thresholds. To identify a suitable threshold for synergism requires a power analysis in reverse, where the probability of detecting a range of effect sizes is quantified across different hypothetical experimental designs (i.e. sample sizes). However, power analysis requires assumptions about variance between replicates (here the separate tubes for each treatment). Given reasonable assumptions about variance, the minimum difference in mortality that can be reliably detected can be outlined for a standard 4x4 Tube assay.

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 it
