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

backgroundThe pathophysiology of ovarian hyperstimulation syndrome (OHSS) is largely unknown. High ovarian response is acknowledged as a risk factor. However, in our clinical practice, the incidence of OHSS is not necessarily linked to the degree of such response among women. Here, we aimed to screen for potential risk factors other than those associated with ovarian response.

methodsA total of 21,222 ovarian stimulation cycles were collected among women undergoing assisted reproductive technology, among which 84 patients with late-onset OHSS were identified as cases; corresponding matched control cases were obtained from the remaining 21,138 cycles. A multivariable logistic regression with the best subset method was performed to screen for significant risk factors.

resultsFirst, control samples were obtained with a case-to-control ratio of 1:4. The matching criteria were mainly ovarian response-related factors including age, body mass index, number of oocytes retrieved, standard or mild ovarian stimulation, and specific ovarian stimulation protocols. After matching the five ovarian response-related factors, 81 cases and 318 controls were obtained. The best model was selected after analysis as above. Basal serum low-density lipoprotein cholesterol (LDL-C), basal total cholesterol (TC), and estradiol (E
