“…We estimated adjusted odds ratios (aORs) for new-onset long COVID using logistic regression, comparing second to first infections, controlling for sociodemographic characteristics and calendar date of infection, plus vaccination status in participants ≥16 years of age. …”

Risk of hand osteoarthritis in new users of hormone replacement therapy: a nested case-control analysis by Burkard, T, Rauch, M, Spoendlin, J, Prieto-Alhambra, D, Jick, SS, Meier, CR

“…We matched women with incident HOA during follow-up (cases) to osteoarthritisfree controls on age and calendar date (index date, ID), in a ratio of 1:4. We applied conditional logistic regression to calculate odds ratios (OR) with 95 % confidence intervals (CI) of HOA associated with new HRT use compared with non-use overall, and for women with recorded menopause we calculated separate ORs according to the time between menopause and HRT initiation (current users), and the time between HRT cessation and the ID (past users), versus non-users.…”

Relative sea-level changes in Crete: reassessment of radiocarbon dates from Sphakia and West Crete by Price, S, Higham, T, Nixon, L, Moody, J

“…These new radiocarbon dates are analysed using Bayesian statistics. The resulting calendar dates for changes in sea level are younger than previously assumed. …”

Fluctuating radiocarbon offsets observed in the southern Levant and implications for archaeological chronology debates by Manning, S, Griggs, C, Lorentzen, B, Ramsey, C, Chivall, D, Jull, A, Lange, T

“…We measured 14C ages of calendar-dated tree-rings from AD1610 to 1940 from southern Jordan to investigate contemporary 14C levels and to compare these with IntCal13. …”

Climate and the individual: inter−annual variation in the autumnal activity of the european badger by Buesching, S, Macdonald, D

“…When compared on the same calendar dates, to control for night length, duration of mean badger nightly activity was longer (9.5 hrs ±3.3 SE) in 2010 than in 2012 (8.3 hrs ±1.9 SE). …”
