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

purposeThis study assessed the outcomes of microsurgical testicular sperm extraction (mTESE) and potential preoperative predictors of sperm retrieval (SR) in patients with non-obstructive azoospermia (NOA). MATERIALS AND

methodsClinical data of 111 NOA patients who underwent mTESE was reviewed retrospectively. Baseline patient characteristics, including age, body mass index (BMI), testicular volumes, and preoperative endocrine levels, such as testosterone (T), follicle-stimulating hormone (FSH), serum-luteinizing hormone (LH), prolactin, sex hormone-binding globulin (SHBG), FSH/LH ratio along with T/LH ratio, were analyzed. After categorizing the patients into two groups based on SR success or failure, logistic regression analysis was performed to identify the preoperative predictors of successful SR.

resultsSixty-eight patients had successful SR (61.3%), whereas 43 patients (38.7%) showed negative results. Failed SR group had elevated serum FSH and LH levels, whereas successful SR patients had a significantly larger testicular volume (

conclusionIn addition to traditional predictors, such as testicular volume and preoperative FSH levels, the T/LH ratio is a potential independent predictor of successful SR in infertile patients with NOA.
