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

objectivesTo evaluate the association between serum iron levels and cervical cancer risk in Chinese populations.

methodsA literature search was conducted using the PubMed, WanFang, and SinoMed databases up to April 30, 2019. Pooled standard mean differences (SMD) and 95% confidence intervals (CI) were analyzed using R software with a random-effects model.

resultsData from nine studies comprising 454 cervical cancer patients and 880 controls were used in the analysis. Our results demonstrated that serum iron levels in cervical cancer patients were significantly lower than those in controls in Chinese populations (summary SMD = -1.24, 95%CI = -1.37 to -1.10;

conclusionsOur findings show that serum iron levels are lower in patients with cervical cancer than in control individuals. However, further high-quality studies are necessary to clarify the role of serum iron levels in cervical cancer risk.
