1 · What the graph read from it

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.

2 · The registry

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

objectiveTo analyze gonadotropin-releasing hormone (GnRH) agonist in association with human chorionic gonadotropin (hCG) (dual triggering) versus hCG alone (conventional triggering) for final oocyte maturation triggering in GnRH antagonist cycles in an unselected population of Brazilian women.

methodsThis prospective case-control study involved 114 patients referred to autologous in vitro fertilization treatment between February 2018 and August 2019, recruited regardless of age, infertility factor or number of cycles. The patients were randomly allocated into two groups according to oocyte maturation triggering approach: group A (n = 48) - hCG only; and group B (n = 66) - hCG plus GnRH agonist. The main outcomes measured were the number of total and metaphase II (MII) oocytes retrieved.

resultsThe groups were homogenous in terms of age. There were no moderate or severe ovarian hyperstimulation syndrome events. There were no statistical differences concerning total or MII oocytes retrieved between the groups (p > 0.05). The MII/total oocyte rate was 70.9% in group A, and 74.5% in group B (p = 0.679). There was no oocyte retrieved in 2/48 patients (4.16%) in group A, 1/66 (1.5%) in group B. There were no MII oocytes in 4/48 patients (8.3%) in group A, and 2/66 (3%) in group B. Age was directly correlated to the number of total and MII oocytes retrieved (p < 0.05).

conclusionsDual triggering was equivalent to conventional hCH triggering in terms of the number of total and MII oocytes retrieved in the general population. Further studies are necessary to ascertain dual triggering indication in selected groups of women.
