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
backgroundThe continual emergence of novel synthetic cathinones poses significant public health concerns due to their unpredictable pharmacological profiles and potential for abuse. Among these, 4-F-3-Me-α-PVP-a newly identified analogue of α-PVP-has recently surfaced on the illicit drug market, yet its biological effects remain uncharacterized.
aimTo provide the first comprehensive pharmacological evaluation of 4-F-3-Me-α-PVP.
methodsIn vitro transporter inhibition was assessed using HEK293 cells expressing human dopamine (DA), norepinephrine, and serotonin transporter (DAT, NET, or SERT). In male rodents, locomotor activity was measured after i.p. (mice) or s.c. (rats) administration. In vivo microdialysis in rats quantified extracellular DA in the nucleus accumbens. Rewarding and reinforcing effects were evaluated using conditioned place preference (CPP) in mice and intravenous self-administration (IVSA) in rats under fixed-ratio and progressive-ratio schedules.
resultsIn vitro assays revealed that 4-F-3-Me-α-PVP acts as a potent DAT and NET inhibitor, with additional, though weaker, activity at SERT. In vivo, 4-F-3-Me-α-PVP significantly increased locomotor activity in male rodents (10 and 30 mg/kg in mice; 3 mg/kg in rats). Importantly, 4-F-3-Me-α-PVP also increased extracellular DA levels in the rat nucleus accumbens (3 mg/kg, s.c.), pointing to its potential for abuse. Behavioral assays further demonstrated rewarding and reinforcing effects in rodents, with significant CPP in mice at all doses tested and dose-dependent IVSA in rats observed under both fixed-ratio and progressive-ratio schedules.
conclusionsCollectively, these findings indicate that 4-F-3-Me-α-PVP possesses substantial psychostimulant and abuse-related effects in rodents, underscoring the need for regulatory vigilance and continued investigation into emerging synthetic cathinones.
