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 explore the clinical characteristics, and the effect of paroxysmal nocturnal hemoglobinuria (PNH) clone size and its evolution on response and survival in aplastic anemia (AA) patients.
methodsThe clinical data of 90 AA cases with PNH clones from 316 AA patients between January 2011 and September 2014 were retrospectively reviewed, their clinical characteristics were analyzed, and the influence of PNH clone evolution and size on response and survival were explored.
results① Of 316 patients, 90 cases (28.5%) with PNH clones. Of 83 cases with long-term follow-up data available, the complete (CR) and partial response (PR) rates were 43.4% and 33.7% respectively, with the overall responsive rate of 77.1%. The 3-year and 5-year overall survival (OS)rates were 79.4% and 76.1% respectively. ② After immunosuppressive therapy (IST), the PNH clone changed from negative to positive in 24 cases, persistently positive PNH clones were observed in 22 cases, disappeared in 10 cases. There were no significant differences in terms of overall responsive rates, survival rates, absolute reticulocyte value, TBIL, IBIL and LDH among the three groups (P >0.05). Ten cases became AA-PNH after a median time of 15.6 months, no significant differences were found in overall responsive and survival rates between the 10 cases and the other 46 cases who were monitored for PNH clones (P values were 0.896, 0.688, respectively). ③ According to univariate analysis, age≥55, infection, VSAA, ANC <0.5 × 10(9)/L and absolute reticulocyte value <0.012 × 10(12)/L had significant influence on survival (P values were 0.026, 0.000, 0.001, 0.000 and 0.010, respectively). Cox regression model analysis identified that age, infection and ANC were independent prognostic factors affecting survival (P values were 0.050, 0.012 and 0.050, respectively). The PNH clone size had no significant influence on response and survival based on univariate and Cox analyses.
conclusionThe PNH clone size and its evolution had no significant influence on response and survival.
