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
Photodynamic therapy (PDT) damages cancer cells via photosensitization using harmless laser irradiation. We synthesized a new photosensitizer, mannose-conjugated-chlorin e6 (M-chlorin e6), which targets mannose receptors that are highly expressed on M2-like tumor-associated macrophages (M2-TAMs) and cancer cells. In our previous study, we demonstrated that M-chlorin e6 PDT reduces tumor volume and decreases the proportion of M2-TAMs. Whether M-chlorin e6 PDT-treated cancer cells activate tumor immunity remains unclear, although the decrease in M2-TAMs is thought to be a direct injurious effect of M-chlorin e6 PDT. Calreticulin (CRT) is exposed at the surface of the membrane of cancer cells in response to treatment with chemotherapeutic agents such as anthracycline and oxaliplatin. Surface-exposed CRT induces phagocytosis of CRT receptor-positive cells, including macrophages, inducing anticancer immune responses. In the present study, we found that M-chlorin e6 PDT increases CRT on the surface of cancer cells, leading to macrophage phagocytosis of cancer cells. Furthermore, M-chlorin e6 PDT increases CD80
