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

backgroundManaging chest tubes before removal remains a controversial clinical issue. Clamping a chest tube before removal is a common practice and is often used to assess latent air leaks.

methodsWe systematically searched MEDLINE/PubMed, Embase, Scopus, and Web of Science from inception to 11 February 2026 for studies comparing clamping versus no clamping before chest-tube removal. Two reviewers independently screened and extracted data. Random effect meta-analyses used REML with Hartung-Knapp adjustment, pooling risk ratios for pneumothorax and re-intervention, and mean differences (days) for hospital length of stay.

resultsThe results of this study show no significant differences between the clamping vs. no-clamping in terms of pneumothorax/hemothorax recurrence, re-intervention rates, or hospital length of stay.

conclusionWithin different causes of applying chest tube/ chest drain, routine clamping before chest-tube removal did not reduce early recurrence or the need for re-intervention.
