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

backgroundStroke, either due to ischemia or hemorrhage, causes acute neurological damages to the brain. There is shortage of reliable biomarkers for ischemic stroke (IS), and we therefore investigated the serum concentrations of microRNA-210 (miR-210) and hypoxia inducible factor-1α (HIF-1α), as possible diagnostic and/or prognostic markers for IS.

methodsSerum samples were acquired from 52 IS patients and their healthy counterparts at five time points: upon admission, 24 and 48 h after admission, upon discharge and 3 months later. Serum levels of miR-210 and HIF-1α were respectively analyzed using real time RT-PCR and ELISA. Diagnostic and prognostic accuracy tests were performed to assess the value of suggested biomarkers.

resultsIS patients demonstrated higher levels of serum HIF-1α and lower miR-210 in comparison to the healthy subjects. MiR-210 was suggested to be a weak diagnostic biomarker at the time of admission (AUC = 0.61; p = 0.05), while HIF-1α was an acceptable diagnostic marker for IS (AUC = 0.73; p < 0.0001). The higher expression of miR-210 and lower levels of HIF-1α were associated with better survivals in IS patients.

conclusionsSerum miR-210 is a weak diagnostic marker of IS. Serum HIF-1α is a better biomarker in diagnosing IS patients but further work in larger groups, including those with hemorrhagic stroke is necessary to confirm its diagnostic utility. Similarly, the prognostic potentiality of miR-210 and HIF-1α was acceptable but needs bigger sample size and longer follow-up to be statistically confirmed.
