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
The aim of the study was to assess whether SMS reminders to patients on Vit K antagonists(VKA) improved adherence to INR testing as compared to clinic based follow up. The study was a parallel group randomized open label single center study carried out at a tertiary care hospital in North India from Oct 2018 to Nov 2019. The interventional arm received SMS in Hindi or English on two consecutive days prior to scheduled INR testing. Primary outcome was percentage of patients adhering to regular INR testing in two groups. Secondary outcomes included time in therapeutic range(TTR) for each patient and proportion of patients having TTR of more than 60% by percentage method. 111 patients were screened and 98 were randomized into two groups (49 each group). In the control group 13(26.5%) as compared to 32(78%) in the intervention group were adherent to regular INR testing, the result was statistically significant ( Supplementary Information: The online version contains supplementary material available at 10.1007/s12288-025-01995-z.
