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

contextAlthough adequate luteal hormone production is essential for establishing pregnancy, luteal phase deficiency (LPD) is poorly characterized among eumenorrheic women.

objectiveWe assessed the prevalence and overlap of two established LPD diagnostic criteria: short luteal phase duration less than10 days (clinical LPD) and suboptimal luteal progesterone of 5 ng/mL or less (biochemical LPD) and their relationship with reproductive hormone concentrations. DESIGN, SETTING, AND

participantsWe conducted a prospective study in western New York (2005-2007) following 259 women, aged 18-44 years, for up to two menstrual cycles.

resultsAmong ovulatory cycles with recorded cycle lengths (n = 463), there were 41 cycles (8.9%) with clinical LPD, 39 cycles (8.4%) with biochemical LPD, and 20 cycles (4.3%) meeting both criteria. Recurrent clinical and biochemical LPD was observed in eight (3.4%) and five (2.1%) women, respectively. Clinical and biochemical LPD were each associated with lower follicular estradiol (both P ≤ .001) and luteal estradiol (P = .03 and P = .02, respectively) after adjusting for age, race, and percentage body fat. Clinical, but not biochemical, LPD was associated with lower LH and FSH across all phases of the cycle (P ≤ .001).

conclusionsClinical and biochemical LPD were evident among regularly menstruating women. Estradiol was lower in LPD cycles under either criterion, but LH and FSH were lower only in association with shortened luteal phase (ie, clinical LPD), indicating that clinical and biochemical LPD may reflect different underlying mechanisms. Identifying ovulation in combination with a well-timed luteal progesterone measurement may serve as a cost-effective and specific tool for LPD assessment by clinicians and researchers.
