The effect of ovulation synchronization with OvuGel on ovarian follicles and fertility responses to a single fixed time insemination in different parities and seasons.

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
Increasing use of semen from superior sires can accelerate genetic improvement when using a single fixed-time AI (SFTAI) to reduce the number of sperm required to produce a litter. The objectives of this study were to: 1) Assess whether follicle development, ovulation, and insemination was altered by parity and season in OvuGel and Controls; 2) Determine the impact of Day of OvuGel administration and estrus in Controls; and 3) Evaluate OvuGel and Control interactions with parity and season on farrowing rate and litter size. The experiment was performed in replicates in summer and fall with sows assigned from Monday and Thursday wean groups by parity to OvuGel or Control after weaning (Day 0). Sows received OvuGel (n = 1,636) on Days 3, 4 or 5 based on proestrus or estrus symptoms and then a SFTAI 24 h later. Controls with a wean to estrus interval of 3 to 6 d (n = 1,676) received an AI on each day standing. Ovaries of a sub-population of the Thursday weaned sows (n = 445) were scanned by ultrasound. The number (17.5) and size (7.0 mm) of ovulatory follicles on Day 4 did not differ between treatments, but P1 and P2 sows had smaller follicles and sows weaned in Sep-Oct had fewer and smaller sized follicles (
