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

backgroundMetformin, an anti-diabetes drug, is always used as a first-line agent for the management of T2DM. This meta-analysis was conducted to investigate whether CRP was sensitive in predicting the efficacy of metformin in the treatment of T2DM.

methodsPotential relevant studies were identified covering the following databases: MEDLINE, Science Citation Index database, the Cochrane Library Database, PubMed, EMBASE, CINAHL, Current Contents Index, the Chinese Biomedical Database, the Chinese Journal Full-Text Database, and the Weipu Journal Database. Data from eligible studies were extracted and included into the meta-analysis using a random effects model. Statistical analyses were calculated using the version 12.0 STATA software.

resultsA total of 33 articles including 1,433 subjects were collected for analysis. Pooled SMD of those studies revealed that serum levels of CRP and hs-CRP significantly decreased in patients with T2DM after receiving the metformin treatment. Subgroup analysis by country yielded significant different estimates in the serum levels of CRP between the baseline and after metformin treatment in the China, Israel and India subgroups; but only detected only in the China subgroup considering serum levels of hs-CRP. Follow-up time-stratified analyses indicated that serum levels of CRP were markedly reduced in the metformin-treated group in all subgroups. While differences in serum hs-CRP levels were not observed in two subgroups.

conclusionDecreased serum levels of CRP and hs-CRP may contribute to a more sensitive prediction in providing a more accurate efficacy reference in the metformin drug in T2DM patients.
