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

backgroundBone marrow of patients with aplastic anemia (AA) is different from that of patients with myelodysplastic syndrome (MDS) and is difficult to identify by blood examination. IDEAL-IQ (iterative decomposition of water and fat with echo asymmetry and least-squares estimation) imaging might be able to quantify fat fraction (FF) and iron content in bone tissues. PURPOSE: To determine if IDEAL-IQ measurements of bone marrow FF and iron content can distinguish between patients with AA and MDS. STUDY TYPE: Retrospective. POPULATION: Fifty-seven patients with AA, 21 patients with MDS, and 24 healthy controls. FIELD STRENGTH/SEQUENCE: 3.0 T, IDEAL-IQ sequence. ASSESSMENT: Three independent observers evaluated the IDEAL-IQ images and measured FF and R2* in the left posterior superior iliac spine. STATISTICAL TESTS: Kruskal-Wallis test, linear correlations, and Bland-Altman analysis were used. A P-value of <0.05 was considered statistically significant.

resultsThe FF in patients with AA (79.46% ± 15.00%) was significantly higher than that in patients with MDS (42.78% ± 30.09%) and control subjects (65.50% ± 14.73%). However, there was no significant difference in FF between control subjects and patients with MDS (P = 0.439). The R2* value of AA, MDS, and controls was 145.38 ± 53.33, (171.13 ± 100.89, and 135.99 ± 32.41/second, respectively, with no significant difference between the three groups (P = 0.553). DATA

conclusionQuantitative IDEAL-IQ magnetic resonance imaging may facilitate the diagnosis of AA and distinguish it from MDS. LEVEL OF EVIDENCE: 3 TECHNICAL EFFICACY STAGE: 2.
