1 · What the graph read from 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.

2 · The registry

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

backgroundABO blood group has been linked with a number of diseases including cancer. Association of ABO blood type with esophageal squamous cell carcinoma (ESCC) has been sparsely reported and the results are inconsistent. We undertook this study to analyze if any association exists between the ABO and Rh blood groups and ESCC risk.

methodsWe conducted a hospital-based case control study to analyze ABO and Rh blood groups in patients with histologically proven diagnosis of ESCC and compared them with healthy donors from the same population. ABO and Rh blood group status of general population was obtained from the blood bank at Sher-i-Kashmir Institute of Medical Sciences (SKIMS) and from original articles published from time to time. Chi-Square test was performed to look for statistical significance.

resultsFor this study, 206 patients were prospectively enrolled. Seventy-four (35.9%) patients had blood group O. Blood groups type A and type B was found each in 59 (28.6%) patients. In 108,014 healthy donors, 35.3% had blood type O followed by type B (33.66%). There was no significant difference in any of the blood types between patients with ESCC and donors (P = 0.31).

conclusionNo association exists between ABO blood type and the risk of ESCC.
