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

purposeType 2 diabetes mellitus (T2DM) patients treated with metformin are predisposed to develop contrast-induced nephropathy (CIN) after received emergency contrast-enhanced computed tomography (CT) examination. We evaluated the protective effects of alprostadil on CIN in T2DM patients treated with metformin after contrast media (CM) administration.

methodsIn this single-institution, single-blind, superiority trial, we randomly assigned 451 T2DM patients taking metformin and underwent emergency contrast-enhanced CT examination to either the alprostadil group (227 patients) receiving alprostadil or the control group (224 patients) without alprostadil. All subjects stopped taking metformin and drank 500 ml water within 12 h after CM exposure. In addition, patients in the alprostadil group were injected with alprostadil (10 μg/day, for 3 days) plus 20 ml normal saline (alprostadil hydration) and the control group patients were daily injected with 20 ml normal saline as control for 3 days following CM administration. Serum creatinine (Scr) was measured before and <72 h after contrast-enhanced CT examination. CIN was defined as an increase in Scr ≥ 44.2 µmol/l (0.5 mg/dL) or >25% over baseline within 3 days of contrast administration.

resultsThere was a lower incidence of CIN in patients underwent alprostadil hydration than drinking water monohydration after CM administration, who with either normal renal function or chronic kidney disease (baseline eGFR < 60 ml·min

conclusionsAlprostadil hydration was superior to drinking water monohydration regarding preventing CIN in T2DM patients treated with metformin after contrast-enhanced CT.
