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 investigate the role of baseline gonadotropins in predicting the biochemical response to clomiphene citrate (CC) treatment.

methodsWe conducted a retrospective review of data from hypogonadal men treated with CC in 2 high-volume fertility centers between 2013 and 2018. Patient age, body mass index, and baseline hormones (follicle stimulating hormone [FSH], luteinizing hormone [LH], and total testosterone [TT]) were obtained. Response to treatment was measured as changes in TT levels within 6 months of initiating CC treatment. Linear regression models adjusted for age, body mass index, and time on CC therapy were fitted to assess the associations between baseline LH and FSH levels with treatment response.

resultsA total of 332 men with mean ± standard deviation age of 36.2 ± 8.2 years were included. Median time to initial follow-up was 6 weeks (25th-75th interquartile range [IQR]: 4-9 weeks). TT levels increased significantly on CC treatment (mean change: 329.2 ng/dL, 95% CI: 307.4-351.0) with 73% of men having at least 200 ng/dL increase over baseline TT levels. In univariable linear regression models, only age was significantly associated with TT response. Neither the baseline LH nor FSH significantly predicted TT response in linear regression models.

conclusionCC treatment results in significant increases in testosterone levels in most men. Baseline gonadotropins are not strong predictors for treatment response to CC. Adequate biochemical response with CC trial can be expected in most patients with normal or slightly elevated baseline gonadotropin levels.
