Trial report in Zhonghua xue ye xue za zhi = Zhonghua xueyexue zazhi, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper, 1 of them a synthesis that pooled 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.
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 evaluate the efficacy and safety of anagrelide in essential thrombocythemia (ET).
methodsPatients who diagnosed as ET according to the World Health Organization classification were enrolled. Each patient was assigned to take anagrelide hydrochloride capsule or hydroxyurea tablet by random 1∶1 ratio. Dose of anagrelide started at 2 mg/d, then increased gradually and the maximum dose was 10 mg/d until the platelet counts dropped to (100-400) × 10⁹/L, one month later gradually reduced to maintain dose. The dose of hydroxyurea was 1000 mg/d at beginning, then increased gradually, when platelet counts dropped to (100-400)×10⁹/L and kept for one month, reduced to maintain dose as 10 mg·kg⁻¹·d⁻¹. The observation period was 12 weeks.
resultsA total of 222 patients were enrolled in seventeen centers (including 113 patients treated with anagrelide and 109 with hydroxyurea). Therapy efficacy can be evaluated in 198 patients (including 97 patients administered with anagrelide and 101 with hydroxyurea). At 12th weeks of therapy, the hematologic remission rate was 87.63% (85/97) in anagrelide group and 88.12% (89/107) in hydroxyurea group, the differences between the two groups were not significant (P=0.173). Treatment with anagrelide lowered the platelet counts by a median of 393 (362-1 339) × 10⁹/L from a median of 827 (562-1657) × 109/L at the beginning of the observation to 400(127-1130)×10⁹/L after 12 weeks (P<0.001), which were similar to the treatment result of hydroxyurea by a median drop of 398 (597-1846)× 10⁹/L (P=0.982). The median time to achieving response of anagrelide group was 7 (3-14) days, superior to that of hydroxyurea for 21 (14-28) significantly (P=0.003). Frequency of anagrelide related adverse events was 65.49 % (74/113), including cardiopalmus (36.28% ), headache (21.24% ), fatigue (14.16% ) and dizzy (11.50% ).
conclusionAnagrelide was effective in patients with ET which had similar hematologic remission rate to hydroxyurea and could take effect more quickly than hydroxyurea. Incidence of adverse events was undifferentiated between anagrelide and hydroxyurea, but anagrelide treatment had tolerable adverse effects and no hematologic toxicity.
