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.

Abstract

contextHuman granulosa cells (GC) acquire LH receptor (LHR) expression during the follicular phase of the menstrual cycle. Currently, the precise follicular stage is unknown, and specific roles of LH in the follicular development are not fully understood.

objectiveOur objective was to measure LHR gene expression on GC and cumulus cells (CC) from normal human follicles with diameters form 3-20 mm. DESIGN, SETTING, AND PATIENTS: At a university hospital, GC, CC, and the corresponding follicular fluid (FF) were collected from patients undergoing fertility preservation by having one ovary frozen and patients undergoing infertility treatment.

interventionsCells and fluids were isolated from surgically excised ovaries or from aspirated preovulatory follicles.

main outcome measuresWe evaluated gene expression of LHR, FSHR, androgen receptor (AR), aromatase (CYP19a1), and AMHR2 normalized to the GAPDH expression and associated with FF levels of anti-Mullerian hormone, inhibin-B, and steroids.

resultsLHR expression was maximal in GC from preovulatory follicles before ovulation induction. A majority of 150 antral follicles (3-10 mm in diameter) showed LHR expression at approximately 10% of the maximum, and LHR expression showed significant associations with FSHR, AR, CYP19a1, and AMHR2 and with FF estradiol and progesterone. Levels of FSHR continued to decline in GC as the follicular diameter increased.

conclusionsThe LHR gene is expressed in GC of human antral follicles throughout the follicular phase and is significantly associated with expression of the CYP19a1 gene and with the corresponding FF concentrations of estradiol and progesterone. LH appears to affect human follicular development during most the follicular phase in normal women.
