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

A 65-year-old man, who had undergone laryngectomy two years earlier, was incidentally found to have nodular shadows and ground-glass opacity (GGO) in both lower lobes, identified nine months ago, which gradually progressed. He was diagnosed with lipoid pneumonia based on a transbronchial lung biopsy. The daily application of Vaseline to the tracheostomy site was considered the cause of exogenous lipoid pneumonia. Although GGO improved after the discontinuation of Vaseline use, it persisted 2 years later. This case is notable for its unusually short onset interval of 1.5 years and the longest reported follow-up of Vaseline-induced lipoid pneumonia after laryngectomy.
