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

Many investigations have demonstrated the prophylactic effect of Nigella sativa on asthma disease. One of its active constituents is α-hederin. In the present study, the preventive effect of two different concentrations of α-hederin on tracheal responsiveness and lung inflammation in ovalbumin-sensitized guinea pigs was examined. Forty male adult Dunkin-Hartley guinea pigs were randomly divided into the control (C), sensitized (S) and sensitized pretreated groups with thymoquinone (3 mg/kg i.p., S + TQ), low-dose α-hederin (0.3 mg/kg i.p., S + LAH) and high-dose α-hederin (3 mg/kg i.p., S + HAH). The responsiveness of tracheal smooth muscle (TR) to methacholine, histamine and ovalbumin was assessed. Moreover, total and differential white blood cell counts in lung lavage fluid were examined. Compared with the S group, the mean EC50 value in the S + LAH group increased significantly (p < 0.05). The mean EC50 value of histamine contraction in the S + LAH and S + HAH groups was significantly higher than in the S group (p < 0.05). In all pretreated groups, the TR to ovalbumin decreased in comparison to the S group (p < 0.001). Both the S + HAH and S + LAH groups showed significantly decreased TR compared to the S + TQ group (p < 0.01-p < 0.01). Total WBC and eosinophil counts in all pretreated groups decreased significantly in comparison with the S group (0.001-0.01). There was a significant increase in neutrophil, lymphocyte and monocyte counts in the pretreated groups compared to the S group (p < 0.001-p < 0.05). The basophil count in the S + TQ and S + HAH groups was significantly lower than in the S group (p < 0.01-p < 0.05). This study suggested that α-hederin has anti-inflammatory and bronchodilatory effects like thymoquinone.
