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.
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
backgroundScorpion envenomation is a worldwide problem, especially in tropical and subtropical areas like Egypt. Scorpion envenomation is responsible for the high mortality rate all over the world, which makes much research carried out to see the efficacy of other drugs as supportive treatment in addition to antivenom.
aimTo see the efficacy of prazosin drug with scorpion antivenom compared to antivenom alone.
methodsIt is a prospective randomized comparative study between two groups from February 2023 to July 2024. Each group is 50 cases to compare the efficacy of prazosin with antivenom (group 1) and the antivenom alone (group 2) in scorpion stings cases.
resultsThe median age of the 100 cases was 7 years old. 54% of the study population were males. 46% of cases were females. Most of the cases were from rural areas. There was no significant difference in age, sex, and the patients' residence between the two groups. There was no significant difference between the 2 groups regarding the duration of stay in the hospital till mortality or discharge, with a median of 3 days in each group. However, there was a significant difference in the antivenom received in each case between the 2 groups, with a median of 6 vials in group 1 and 9 vials in group 2. Mortality and complications were observed to occur more in group 2 than in group 1 despite the insignificant p values. The study's mortality rate was 14%, 4/50 (8%) in group 1 and 10/50 (20%) in group 2. The number of antivenoms significantly increased with an increase in duration of stay, heart rate, respiratory rate, troponin level, and mortality outcome. While the number of antivenoms significantly decreased with the rise in systolic and diastolic blood pressure. CONCLUSION AND RECOMMENDATIONS: The study concluded that prazosin can be added to antivenom to increase its efficacy and decrease the number of needed antivenoms. Prazosin is a safe drug when used with precautions to avoid the first-dose phenomenon. Prazosin decreases complications and mortality when added to antivenom, but not significantly. The study recommends using prazosin with precautions for all manifested scorpion cases with antivenoms to increase the efficacy of the antivenom and treat the adrenergic manifestation.
