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

<p>Introduction: The purpose of this study was to evaluate the effect of biperiden on nicotine craving in a proof-of-concept clinical study.

methodThe study involved 46 male participants (mean age: 45.3 ± 9.31 years) who smoked an average of 20.8 (10.0) cigarettes per day. Participants were randomly assigned to either a biperiden (4 mg/day) or placebo group, with treatment lasting 7 days. The outcomes were assessed at baseline (T0) and after 7 days (T1) using self-reported questionnaires, including the Questionnaire of Smoking Urges-Brief, the Fagerström Tolerance Questionnaire, and the Beck Anxiety and Depression Inventories.

resultsRepeated measures ANOVA revealed a significant time × treatment interaction between cigarette consumption (p < 0.001, <inline-formula><mml:math id="m1" xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mrow><mml:msubsup><mml:mi>η</mml:mi><mml:mi mathvariant="normal">p</mml:mi><mml:mn>2</mml:mn></mml:msubsup></mml:mrow></mml:math></inline-formula> = 0.340) and craving (p = 0.002, <inline-formula><mml:math id="m2" xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mrow><mml:msubsup><mml:mi>η</mml:mi><mml:mi mathvariant="normal">p</mml:mi><mml:mn>2</mml:mn></mml:msubsup></mml:mrow></mml:math></inline-formula> = 0.203), indicating that participants in the biperiden group showed greater reductions than those receiving placebo. For dependence, anxiety, and depression, only the main effect of time was significant (p < 0.05), suggesting general improvement across both groups. Ethnicity did not significantly influence any outcomes, and no relevant adverse effects were reported.

conclusionsThese findings suggest that biperiden may represent a promising pharmacological approach for reducing nicotine craving. Further studies with prolonged administration are warranted to evaluate its therapeutic potential for smoking cessation. </p>.
