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 evaluate various methods of operative sperm retrieval in men with non-obstructive azoospermia (NOA) and to determine the optimal surgical approach in terms of effectiveness, morbidity, and complications. MATERIALS AND

methodsPubMed and Cochrane databases were searched to identify five recent reviews and meta-analyses evaluating outcomes for sperm retrieval in men with NOA. RESULTS AND

conclusionMicro-TESE is the most efficient method for retrieving sperm but requires special expertise and can be traumatic for the testes. Conventional biopsies are twice more likely to retrieve sperm than fine-needle aspiration. Testicular aspiration performed by multiple passes into the testis is traumatic and is not efficient for sperm retrieval. Needle-aspiration biopsy and open real-time testicular mapping by the single seminiferous tubule technique can offer less traumatic methods for sperm retrieval, which can be tried before proceeding to micro-TESE. The first attempt at sperm retrieval is the best chance the patient has and should combine various techniques sequentially to give the highest chance of success with the least morbidity.
