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

Pneumococcal meningitis is a serious infection of the central nervous system (CNS) with high fatality rates that causes reduced psychomotor performance, slight mental slowness, impairments in attention executive functions and learning and memory deficiencies. Previously, we demonstrated a correlation between memory impairment and decreased levels of brain-derived neurotropic factor (BDNF) in the hippocampi of rats subjected to pneumococcal meningitis. Emerging evidence demonstrates that histone acetylation regulates neurotrophins; therefore, a potential molecular intervention against cognitive impairment in bacterial meningitis may be the histone deacetylase (HDAC) inhibitor, sodium butyrate, which stimulates the acetylation of histones and increases BDNF expression. In this study, animals received either artificial cerebrospinal fluid as a placebo or a Streptococcus pneumoniae suspension at a concentration of 5 × 10(9) colony-forming units (CFU/mL). The animals received antibiotic treatment as usual and received saline or sodium butyrate as an adjuvant treatment. Ten days after, meningitis was induced; the animals were subjected to open-field habituation and the step-down inhibitory avoidance task. Immediately after these behavioural tasks, the animals were killed, and their hippocampi were removed to evaluate the expression of BDNF, nerve growth factor (NGF) and glial cell line-derived neurotrophic factor (GDNF). In the meningitis group that received saline, the animals presented memory impairment in both behavioural tasks, and hippocampal BDNF and GDNF expression was decreased. Sodium butyrate was able to prevent memory impairment and re-establish hippocampal neurotrophin expression in experimental pneumococcal meningitis.
