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

backgroundInfluence of tuberculosis (TB) on the natural course of COPD has not been well known. This study was designed to investigate the effects of history of TB on the long-term course of COPD.

methodsPatients hospitalized with COPD exacerbation were consecutively included (n=598). Cases were classified into two categories: those with TB history and those without. Clinical, demographic, and radiological features were meticulously recorded, and patients were followed up for hospitalizations due to exacerbation and for overall mortality.

resultsA total of 93 patients (15%) had a history of TB. On average, patients with past TB history were 4 years younger than the rest of the patients (

conclusionOur results showed that a history of TB caused more hospitalizations, reduced respiratory functions and increased PaCO
