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

Smoking negatively impacts aerobic capacity, primarily by reducing V̇O2max, the gold standard measure of cardiorespiratory fitness. While smoking cessation is known to improve vascular function, exercise performance, and oxygen uptake, its specific impact on V̇O2max remains underexplored. Specifically, no research has yet evaluated V̇O2max changes following a switch to electronic cigarettes (ECs) or heated tobacco products (HTPs). This is a secondary analysis of the CEASEFIRE trial, a 12-weeks randomized controlled switching trial comparing the impact of ECs or HTPs on changes in smoking behaviour. The trial offers a unique opportunity to prospectively examine the relationship between smoking behavior and aerobic capacity, and to examine-for the first time-the specific impact of exclusive EC or HTP use on V̇O2max. Changes in VO₂max were analized across three smoking phenotypes: continuous smokers, those who reduced smoking, and those who abstained from smoking Additionally, VO2max was also evaluated specifically in participants who completely abstained from smoking tobacco cigarettes, evaluating outcomes in exclusive EC and HTP users. Quitters showed the greatest improvement in VO2max at both week 4 (2.4 ± 1.7 mL kg
