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

backgroundDisease presentation and outcomes differ by race in a number of malignancies, but data in adult acute myeloid leukemia (AML) are limited. MATERIALS AND

methodsWe conducted a retrospective analysis of pretreatment characteristics, referral and treatment patterns, and outcomes in 548 AML patients evaluated at the University of Maryland Greenebaum Cancer Center, a tertiary care referral center in Baltimore, MD, from 2000 through 2009. Cases were analyzed for time from diagnosis to referral, age, race, gender, socioeconomic status, antecedent hematologic disorder, cytotoxic or radiation therapy for prior malignancy, karyotype, fms-like tyrosine kinase receptor-3 (FLT3) mutations, intensive chemotherapy, clinical trial participation, hematopoietic stem cell transplantation (HSCT) and overall survival (OS).

resultsBlack patients (n=105) were younger than white patients (n=396) (54 vs. 61 years, p<0.001), were more commonly female (55% vs. 45%, p<0.001), and had a lower estimated median household income ($42,677 vs. $53,534 per year, p<0.001). Black patients more frequently had complex karyotypes (26% vs. 12%, p=0.002) and less frequently normal karyotypes (27% vs. 42%, p=0.02). FLT3 mutation frequency was similar. Time to referral and proportion of patients receiving intensive chemotherapy did not differ, but both clinical trial participation (43% vs. 54%, p=0.04) and HSCT (17% vs. 35% for patients ≤70 years old, p=0.001) were less frequent in blacks than whites. Nevertheless, OS was similar in all black and white patients (median 15 vs. 14 months, p=0.23), and when stratified by age, gender and karyotype risk classification.

conclusionAML presentation and treatment differed in black and white patients, but OS was similar. Black patients appear to have barriers to clinical trial participation and HSCT, and there may be barriers to tertiary care referral for black males.
