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

purposeTo evaluate changes in optical coherence tomography (OCT) parameters and visual function in Tuberculous Meningitis (TBM) patients during a short-term follow-up period. A prospective case-control observational study was performed at a Medical University from August 2020 to July 2021.

methodA study was conducted at a medical institute in Northern India, including 52 patients with TBM who presented within one month of systemic symptoms. Optical Coherence Tomography parameters, retinal nerve fiber layer (RNFL) thickness, central sub-foveal thickness (CST), cube average thickness (CAT), and visual function were evaluated at the time of presentation and after one month of follow-up period.

resultsThe study included 52 TBM patients, the mean age was 27 (51.9%) and 25 (48.1%) years, out of 52 patients, 24 (46.2%) were male, and 28 (53.8%) were female. OCT revealed significant thickening of the RNFL, mean of 108.7 μm in the right eye and 108.69 μm in the left eye after 1 month of diagnosis. No significant difference was found between macular parameters (CST, CAT) and visual functions.

conclusionsOCT biomarkers, particularly RNFL thickness, are significantly altered in TBM patients, indicating its potential as a sensitive marker for monitoring retinal changes. The macula appears to be spared in the early phase of TBM, and visual acuity remains relatively unaffected in the short-term follow-up.
