64-study meta-analysis of struggling readers (grades 3-12) finds an overall effect of g=.59 for comprehension intervention, with significantly higher effects for background-knowledge instruction AND strategy instruction AND researcher-developed measures -- cutting both toward and against Hirsch at once.

Effects were significantly higher when studies used researcher-developed measures, background-knowledge instruction, and strategy instruction -- confirming both the measurement-inflation concern and that strategy instruction is not inert.
“significantly higher effects associated with researcher-developed measures, background knowledge instruction, and strategy instruction”
