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

purposeCigarette smoke continues to be widely used around the world and it contains several substances that can affect the pharmacokinetics and/or pharmacodynamics of medications, altering their safety and effectiveness. The aim of this systematic review was to summarize the scientific evidence regarding possible changes in the pharmacokinetics and/or pharmacodynamics of drugs induced by cigarette smoking, possible mechanisms of action and related effects.

methodsThe systematic review was performed according to the PRISMA Statement and the protocol was registered on the PROSPERO platform (CRD42023477784). Pubmed, Scopus, Web of Science databases were used. We considered observational, semi-experimental or experimental studies written in English and published between January 1, 2000, and November 13, 2024, focused on smoking subjects (healthy volunteers or patients) receiving any kind of medication. Data regarding possible modifications in drugs' pharmacokinetics and/or pharmacodynamics induced by cigarette smoking were assessed. The quality of observational studies and experimental studies was evaluated using the Newcastle-Ottawa Quality Assessment Scale and the Jadad Scale, respectively.

resultsIn total, 37 studies were included, and 31 of them showed relevant modifications in the pharmacokinetics or effects of the drugs in smokers compared to non-smokers. Most of the included studies (n = 20) investigated drugs for psychiatric or neurological disorders, showing a reduction in plasma concentration or an increase in drug clearance in smokers as well as antibiotics metronidazole and cycloserine. Besides, seven articles focused on anticancer drugs indicating an increase in drug metabolism. The remaining articles reported effects of smoking on the metabolism of other drugs, such as cardiovascular drugs, phosphodiesterase 5 inhibitors, local anesthetics and medications for musculoskeletal or chronic obstructive pulmonary diseases. Induction of the cytochrome enzyme CYP1A2 is the most common mechanism mediating the reduction of drug concentrations by cigarette smoking.

conclusionThe results indicate an increased risk of therapeutic failure for smokers and represent further motivation to encourage smoking cessation or attention in formulating personalized therapy.
