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.
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
objectiveTo use the technique of magnetic resonance imaging (MRI) T2* mapping to diagnose and follow-up of patients with iron overload.
methods107 patients who were suspected to have iron overload between 2011.7-2014.3 in Peking Union Medical Colleague Hospital were analyzed retrospectively. Patients had the document of MRI T2* value of liver, heart and pancreas, serum ferritin (SF), transferrin saturation (TS), transfusion amount and other related laboratory tests. T2* values were compared with SF and transfusion amount. T2* values in different organs and their relationship with SF were also evaluated. 10 patients who had been adequately chelated for more than half a year were followed up for their SF and T2* values.
resultsThere were 65 males and 42 females with the median age of 51(8-77)-year-old. They were 50 myelodysplastic syndromes (MDS), 36 aplastic anemia, 10 myelofibrosis, 7 hemachromatosis and 4 thalassemia carriers. Liver T2* value was significantly related to SF (r=0.120, P=0.001), but not related to transfusion amount (r=0.019, P=0.175), whereas cardiac MRI T2* was not related either to SF or to transfusion amount. No correlation of the T2* value was found between liver and heart (r=0.015, P=0.235). 70 patients was detected for liver, heart and pancreas T2* simultaneously. Pancreas T2* was compatible to SF (r=0.061，P=0.039) and cardiac T2* (r=0.110, P=0.005), but not correlated to heptic T2* (r=0.047, P= 0.071) or transfusion amount (r=0.000, P=0.960). For the 10 well-chelated patients, during the half year follow-up period, SF changed significantly from (2 566.5±1 152.2) μg/L before chelation to (1 473.4±803.0) μg/L after chelation(P=0.001), while liver T2* remained the same [(6.0±5.1) ms, (6.3±6.0) ms respectively, P=0.629].
conclusionMRI, although related to SF to some extent, was a valuable additional methods for quantifying iron overload. Iron deposition in different organs might be not related to each other and needed to be evaluated separately. Well-chelation therapy could change SF in half-year follow-up, but T2* change needed longer time to follow-up.
