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

purposeAs the concept of late-onset hypogonadism (LOH) has gained increased attention, the treatment of eugonadal patients with LOH symptom has become a clinical problem. Previous studies have shown the possible benefits of 5-aminolevulinic acid (5-ALA) on the somatic, psychological and sexual functions. We therefore conducted this randomized, double-blind, placebo-controlled study to confirm the efficacy and safety of 5-ALA for LOH symptoms. MATERIALS AND

methodsThirty-two eugonadal subjects with LOH symptoms were randomly divided into a 5-ALA group (n=15) and a placebo group (n=17). Treatment was continued for 8 weeks. The change of the Aging Males' Symptoms (AMS) scale score and several biochemical and endocrinological variables during treatment were compared between the groups.

resultsAfter treatment, the change in the total AMS in the 5-ALA group was significantly greater than that in the placebo group (-7.4±4.7

conclusionsThe intake of 5-ALA for 8 weeks was beneficial for eugonadal patients with symptoms of LOH and no severe TEAEs was experienced. 5-ALA should be considered as an option for those patients.
