No paper paired ozone body mass and reproduction in a 2024 invertebrate data extract

We checked whether a public invertebrate extract could test a larger ozone loss in reproduction than in body mass within the same paper. The selected ozone mass sample had 40 records from nine papers. The reproduction sample had 61 records from 17 other papers. No paper supplied both endpoint classes. An endpoint coefficient after removal of paper intercepts is therefore not identified. No paired paper occurred in either of two regions and two publication periods. Adding weight gain or removing the mass unit rule kept the zero overlap. A broader growth category gave five shared ozone papers, but changed the outcome. An extension to other pollutants gave one shared sulfur dioxide paper and none for nitrogen oxides or particulate matter. These exact counts depend on source labels and extraction coverage. They do not show absent pollution effects or an error in the source meta-analysis. Climate interactions and independent field-period tests could not be made. The package gives code, aggregate evidence, source hashes and independent count checks.
