The evidence, row by row

Each row is a claim the essay makes, then the evidence recorded for it and the source it was checked against. For verified rows that is usually the exact words, where they sit and the day they were read. The label says how far it was checked.

What the labels mean
Verified
Checked against the primary source itself by a checker who did not draft the piece, usually with the exact words, where they sit and the date read.
Executed
A run or observation done for the piece: code, a query, a count, or a check made live in an app. The claim is what it returned. Run records are not published.
Checked
Checked against its source by a separate checker in the older ledger format, which recorded no quote, locator or date.
Reported
Not verified word for word against a primary source: carried from a secondary source, from one that could not be opened in full, or supported only in part. The essay words it accordingly.
Struck
Drafted, checked and removed before publication. Kept here, crossed out, with the reason.
Excluded
Considered and deliberately left out of the piece. Kept here with the reason.

    The authors noted that statistical controls used by many included studies rule out a number of potential confounders; the association held after adjustment, though controlled effect sizes ran lower in magnitude than raw (backs §4 "adjusted for many of these and the association held, but adjustment is not proof")

    "Statistical controls (e.g., age, sex, physical condition, etc.) employed by many of the studies rule out a number of potentially confounding variables that might account for the association between social relationships and mortality" (Discussion); "effect sizes based on data controlling for other variables were lower in magnitude than those based on raw data" (Results)

    A within-person daily study found people reported greater happiness and belonging on days with more weak-tie / acquaintance contact; weak ties relate to social and emotional well-being. OUTCOME = well-being, NOT survival (used in §5 to support breadth, scoped as a different outcome from the mortality meta)

    "In Study 1, students experienced greater happiness and greater feelings of belonging on days when they interacted with more classmates than usual... we again found that weak ties are related to social and emotional well-being. The current results highlight the power of weak ties, suggesting that even social interactions with the more peripheral members of our social networks contribute to our well-being."
