It is most true,1 our study did observe But a selected few; and that this subpart Could from the broader population swerve, Our estimate thus might from truth depart. It is most true, what we with stats compute, Confounded is, whence truth cannot be carved; Adjustment helps, still we do not dispute Some bias stands; of real truth we are starved. True, who was exposed is cloaked indeed, Whereof our measure can be but a shade, That “Treated” were dosed is not guaranteed; True, on earth are no firm deductions made, Skeptics might thus our conclusions reject; True; and yet true, we hope we are correct.
