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

objectiveTo conduct a systematic review investigating the normal age-related changes in lung function in adults without known lung disease.

designSystematic review. DATA SOURCES: MEDLINE, Embase and Cumulative Index to Nursing and Allied Health Literature (CINAHL) were searched for eligible studies from inception to February 12, 2019, supplemented by manual searches of reference lists and clinical trial registries. ELIGIBILITY CRITERIA: We planned to include prospective cohort studies and randomised controlled trials (control arms) that measured changes in lung function over time in asymptomatic adults without known respiratory disease. DATA EXTRACTION AND SYNTHESIS: Two authors independently determined the eligibility of studies, extracted data and assessed the risk of bias of included studies using the modified Newcastle-Ottawa Scale.

resultsFrom 4385 records screened, we identified 16 cohort studies with 31 099 participants. All included studies demonstrated decline in lung function-forced expiratory volume in 1 s (FEV
