1. In 36 of the 40 papers, reproducing the published estimate showed that the analysis behind it computed something other than the paper says, in a way that bears on that estimate: in how a variable was coded (31 papers), the sample analyzed (15), the numbers reported (11), the use of survey weights or design (8), or the model's covariates (5).

2. In 36 of the 40 papers, the investigators recorded at least one departure bearing on the headline estimate, where the computation that reproduces it differs from the paper's description. In 16 of them the paper itself shows one, two of its parts disagreeing or its own printed numbers ruling out what it describes; in 20 more, recomputation from the public files shows one, a computation other than the one described being the one that reproduced the published numbers; none has only departures whose computation is unresolved.
