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

Dregea volubilis (family Asclepediaceae) is widely used as anthelmintic in traditional system of medicine in eastern and southern part of India. The aim of this study was to evaluate the anthelmintic activity of the methanol extract of D. volubilis leaves (MEDV) and to observe its effect through SEM study. Live parasites (trematode Paramphistomum explanatum) were collected from buffalo in 0.9% phosphate-buffered saline (PBS). It was incubated at 37 ± 1°C in media containing either no extract (control), the test drug, MEDV at four dose levels (10, 25, 50, and 100 mg/ml) or the standard drug, albendazole, at a dose of 10 mg/ml. The effectiveness of the extract was judged on the basis of the loss of spontaneous movement and/or complete destruction or death of the trematodes. After being removed from the experimental medium, trematodes were dipped in PBS at 37 ± 1°C and on gentle stimulation, the paralyzed parasite showed immobility. Death was confirmed when it completely lost its motility even when vigorously shaken or dipped in warm water (50°C). The trematodes, both drug treated and others, were further processed for SEM study using standard method. The anthelmintic activity was found with all the doses through paralysis and death of the organisms (p < 0.001). Maximum anthelmintic activity was found with a dose of 100 mg/ml. Minor damage was observed with both suckers, but severe distortion was found with tegumental surface of the treated trematodes. The present SEM-based study established the anthelmintic activity of MEDV.
