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

purposeTo investigate whether the treatment of overt postpartum urinary retention (PUR) with low-intensity pulsed ultrasound (LIPUS) was clinically effective and whether LIPUS could accelerate bladder smooth muscle (BSM) contraction by opening the L-type calcium channels and activating the Ca(2+) signaling pathway.

methodsRecords of 136 patients undergoing PUR were retrospectively reviewed in two different groups for LIPUS and neostigmine between from 2014 to July 2015. The rats BSM strips in vitro were irradiated by LIPUS. The contraction frequency and amplitude were recorded with BL-410F biological experimental system. The BSM cells were constructed and identified by α-actin-specific antibody staining, and the intracellular Ca(2+) concentration was analyzed by flow cytometry.

resultsThe clinical trial indicated that LIPUS had potential therapeutic effect on PUR (80.6 vs. 64.1 %, p < 0.05), and the BSM strip contractility was increased by LIPUS (p < 0.001), and the concentration of Ca(2+) was markedly enhanced by about twofold than that without LIPUS exposure (p < 0.01). Besides, nimodipine could suppress the contraction of BSM and the concentration of intracellular Ca(2+) which was caused by ultrasound.

conclusionsThe results suggested LIPUS had potential therapeutic effect on PUR and the Ca(2+) signaling pathway was involved in the mechanism. The ultrasound irradiation may provide a new method for PUR therapy.
