Quantifying chronic stress in group- and stall-housed sows during gestation using cortisol in hair.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The objective of this study was to characterise chronic stress in gestating sows (n = 66; parity 0-6) housed within the same facility, assigned to gestation stalls or group pens (25 sows per pen) within two days of breeding until day 111 (± 1.4) of gestation using hair cortisol concentrations (HCC) as a biological marker of longer-term stress. Hair was shaved from the right hip at day 6.0 (± 3.8), day 37, day 74, and day 111 of gestation; day 37 and day 111 samples were analysed for cortisol. Housing system, parity class (0-1 [n = 23], 2-3 [n = 17], and 4-6 [n = 26]), and their interactions were explored. Stall-housed parity 0-1 females had higher HCC than all other females regardless of housing system, suggesting that gilts and parity 1 females in stall housing may experience greater chronic stress during gestation.
