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 develop a consensus on histologic human ovarian follicle staging nomenclature, provide guidelines for follicle density calculation, and assess changes due to fixation to enhance communication among clinicians and ovarian biology researchers to gain a deeper understanding of human fertility.

settingBeginning in March 2021, the Ovarian Nomenclature Workshop's Follicle Classification Working Subgroup was organized by the Pediatric and Adolescent Gynecology program of the Eunice Kennedy Shriver National Institute of Child Health and Human Development.

methodsAfter the initial workshop held in May 2021, a Follicle Working Subgroup comprised of experts in reproductive endocrinology and ovarian biology held multiple meetings to develop the human follicle classification system and reported to the collective group during two follow up workshops.

resultsThe Follicle Working Subgroup recommends consolidation and expansion of the current classification systems to include six stages of normal preantral follicles, five stages of normal antral follicles, as well as categories of corpus lutea, abnormal preantral follicles, abnormal antral follicles, and other distinct follicle types. The new preantral staging added intermediate stages (primordial, transitional primordial, primary, transitional primary, secondary, and multilayer ovarian follicles). The antral follicle staging includes early, preselection, selection, dominance, and preovulatory follicles. Abnormal preantral follicles include those with an abnormal oocyte, granulosa cells, or both. We suggest a uniform way of calculating the mean follicle density in the number of follicles/mm

conclusionTo establish a consensus in human ovarian follicle terminology, the Ovarian Follicle Working Subgroup of the National Institute of Child Health and Human Development Ovarian Nomenclature Workshop standardized follicle staging nomenclature and follicle density calculating systems so consistent common language can be used among ovarian biology researchers and clinicians.
