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

Follicular growth, ovulation, and luteinization are influenced by interactions of peptide and steroid hormone-signaling cascades in the ovary. Pituitary adenylate cyclase-activating polypeptide (PACAP) plays an important role in the regulation of several endocrine processes and is present in ovarian follicular fluid (FF). However, little is known about PACAP in FF with regard to maturation, ovulation, fertilization, and successful pregnancy. The aim of this pilot study was to investigate whether there is a correlation between PACAP concentration in FF and ovarian response to superovulation treatment in infertile women, performed in volunteers (n = 132; aged between 20 and 35). After treatment, the number of harvested oocytes was recorded and PACAP immunoreactivity in FF was measured by radioimmunoassay. All the corresponding PACAP concentrations were below 290 fmol/ml in cases when the number of harvested oocytes exceeded 14 per patient, while in all cases above 290 fmol/ml, the number of oocytes was below 14. Using these cutoff values, we determined three study groups: high-PACAP concentration, high-oocyte number, and low-PACAP concentration-low-oocyte number groups. Median values of PACAP concentration in these groups were 411.2, 106.5, and 101.0 fmol/ml, respectively, while the median values of harvested oocytes were 5.5, 19.0, and 5.0, respectively. Differences were significant, indicating a correlation between concentration of PACAP in FF and the number of recruited oocytes. Higher concentrations of PACAP in FF might be associated with lower number of developing oocytes, while low concentrations of PACAP might correlate with a markedly higher number of ova retrieved, thus predicting a higher chance for ovarian hyperstimulation. Our present study is among the first few human clinical studies with direct conclusions drawn for possible clinical impact of PACAP.
