Autoantibodies detection in anti-N-methyl-D-aspartate receptor encephalitis.
Review in Annals of translational medicine, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Autoimmune encephalitis (AE) covers a group of neurological diseases caused by autoantibodies. AE is severe but treatable. It has attracted more and more attention currently. Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is the most common AE characterized by specific autoantibody mainly against NMDAR subunit 1. Cell-based assays (CBA) on human embryonic kidney 293 (HEK293) cells and immunohistochemistry (IHC) on rat brain tissue have been widely used to detect antibody in patients with AE. However, few studies focused on the overview of these assays detecting autoantibodies in AE. Here we reviewed the detection assays in AE and compared the sensitivity and specificity of CBA and IHC. It's found that IHC got a higher positive rate than CBA in both serum and cerebrospinal fluid (CSF) when screening potential AE, while CBA was more specific. Besides, more positive samples were found in CSF than in serum by either IHC or CBA. Hence, both serum and CSF should be sent to detect antibodies by two assays to avoid misdiagnosis. CSF antibody titers were believed more clinically relevant. When positive results were shown in IHC but negative in CBA, other kinds of antibodies associated AE instead of anti-NMDAR encephalitis should be taken into account. Further studies should pay attention to serum testing for diagnosis or assessment of the disease, as CSF testing is invasive and not always available.
