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 summarise the available evidence on frequency of ovarian cyst development during mammalian target of rapamycin inhibitors (mTORi) treatment.

methodsPubMed/Medline and EMBASE databases were searched, from 1990 up to March 2020, using the following keywords: 'tacrolimus', 'sirolimus', 'temsirolimus', 'everolimus', 'deforolimus', 'mTOR' and 'ovarian cysts' (Limit: Human, English, full article). Studies were selected for the review if they met the following criteria: clinical studies, studies reporting original data, studies reporting the number of patients using mTORi, studies reporting the number of patients with ovarian cysts.We selected 7 of 20 retrieved studies. Study design, population, sample size, criteria for diagnosis of ovarian cysts, drug doses and follow-up length were extracted. Pooled estimate of incidence was calculated for ovarian cysts as a percentage, with 95% CI.

resultsFour hundred-six women were included in the selected studies. The pooled incidence was 37.0% (95% CI 16.0% to 58.1%) for all ovarian cysts, and 17.3% (95% CI 5.6% to 29.1%) for clinically significant ovarian cysts. Based on two articles, comparing mTORi and non-mTORi for immunosuppression, pooled OR for ovarian cyst incidence was 4.62 (95% CI 2.58 to 8.28).

conclusionOvarian cyst development is a common adverse event during immunosuppression treatment with mTORi. These cysts are benign conditions, but they require pelvic ultrasound follow-up and in some cases hospital admission and surgery.
