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

purposePatients with diabetes mellitus (DM) often exhibit refractory erectile dysfunction (ED). Red-light-controllable nitric oxide donor (NORD-1) and red-light irradiation have successfully enhanced erectile function in intact rats. In this study, we investigated whether the combination of NORD-1 and red-light irradiation effectively treated ED in streptozotocin (STZ)-treated rats with DM. MATERIALS AND

methodsSeven-week-old male Sprague-Dawley rats were used in this study. Rats in the DM and sham groups received intravenous STZ (50 mg/kg) and saline, respectively. One week after treatment, the blood glucose level of rats in the DM group was >250 mg/dL. Five weeks after the treatment, we performed a functional study by measuring intracavernous pressure (ICP) under cavernous nerve stimulation before and after NORD-1 treatment with and without light irradiation. Additionally, we performed an isometric tension study using the corpus cavernosum of rats treated with NORD-1 or the control compound, SiR650.

resultsThe ICP/mean arterial pressure (MAP) ratio was significantly lower in the DM group than in the sham group before and after NORD-1 treatment without light irradiation (both p<0.05). After NORD-1 treatment with light irradiation, the ICP/MAP ratio in the sham and DM groups was significantly enhanced than before and after NORD-1 treatment without light irradiation (all p<0.05). The ICP/MAP ratio in the DM group after NORD-1 with light irradiation was similar to that in the sham group under normal conditions before NORD-1 treatment. Moreover, the systemic blood pressure was not affected by NORD-1 or light irradiation. In the tension study, the corpus cavernosum of rats treated with SiR650 was not changed by red light in the sham or DM groups. However, the rats treated with NORD-1 were strongly relaxed by red light in both groups.

conclusionsNORD-1 and red-light irradiation could improve ED in the presence of DM without lowering blood pressure.
