PD1 is highly expressed in diffuse large B-cell lymphoma with hepatitis B virus infection.
Article in PloS one, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
objectiveThe purpose of this study was to determine the association between PD1 expression and the clinical prognosis of diffuse large B-cell lymphoma (DLBCL) co-occurring with hepatitis B virus (HBV) infection.
methodsA total of 165 patients presented with newly diagnosed and untreated DLBCL at the First Hospital of Jilin University, Changchun, China, between 2011.01 and 2014.12. Complete clinical information was available for 152 of these 165 patients. We retrospectively reviewed the results of HBV serum marker assays and the clinical information of these 152 DLBCL patients from our hospital database; eventually, only 51 patients were enrolled in this study, and these 51 patients received the PD1 test item.
results① The incidence of HBsAg prevalence was 13.2% (20/152) in this study; ② The incidence of PD1 expression in the HBsAg+ group was 4.3-fold higher than that in the HBsAg-group (40.0% vs 9.4%; P = 0.010); ③ The clinical information, including sex, age, clinical stage, IPI, molecular subtype and chemotherapy status, was analyzed between the HBsAg+ and HBsAg-groups, but there were no significant differences between the two groups; ④ The median OS and PFS of the patients in the HBsAg+ group were 36.5 months and 12 months, respectively; however, the median OS and PFS of patients in the HBsAg-group were not reached (P = 0.033) and 32 months (P = 0.049), respectively; and ⑤ The median OS and PFS of PD1-positive patients in the HBsAg+ group were the worst (24 months and 9 months, respectively), whereas the median OS and PFS of PD1-negative patients in the HBsAg-group were the best (not reached and 32 months, respectively).
conclusionsCompared with patients in the HBsAg-group, the incidence of PD1 expression was significantly higher in the HBsAg+ group, and the median OS and PFS times were the worst in PD1-positive patients in the HBsAg+ group. These results indicated that the dismal prognosis of patients with HBsAg+ may be related to the high rate of PD1 expression. Thus, a targeted PD1 treatment strategy may improve the prognosis of HBsAg+ DLBCL patients.
