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.

Abstract

aimsTo compare the effects of semaglutide and testosterone replacement therapy (TRT) on semen quality and parameters of functional hypogonadism (FH) in men with type 2 diabetes mellitus and obesity. MATERIALS AND

methodsWe designed a randomised open-label trial in 25 men with type 2 diabetes (aged 50 [46-60] years, BMI 35.9 [32.8-38.7] kg/m

resultsThe quality of baseline sperm parameters of our study cohort was poor, below the 5th percentile of reference values. In the SEMA group, there was a significant increase in morphologically normal sperm from baseline to the end of the study (2% [2; 3.5] vs. 4% [2; 5.5]; p = 0.012), whereas sperm concentration and total number decreased significantly in the TRT group. Compared to TRT, the SEMA group had a significantly higher number of morphologically normal sperm, sperm concentration and total number. Both groups experienced an increase in total testosterone and improvement in the AMS score, whereas the IIEF-15 score significantly improved only in the TRT group.

conclusionSemaglutide markedly improved sperm morphology, total testosterone levels and symptoms of hypogonadism. These findings highlight semaglutide's potential as a therapeutic approach for men with obesity-related FH who desire fertility. CLINICAL TRIAL REGISTRATION NUMBER: NCT06489457, www.
