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
Anticholinergic medications can cause constipation in older adults. The Japanese Anticholinergic Risk Scale (JARS), released in May 2024, is not yet sufficiently validated clinically. We examined the association between total anticholinergic burden based on JARS and laxative prescriptions. This cross-sectional study utilized community pharmacy dispensing claims for outpatients aged ≥ 65 years who were registered with a family pharmacist between November 1 and December 31, 2024. Chronic medication use was defined as prescriptions totaling ≥ 28 days during the study period. The primary analysis focused on patients receiving 5-9 concomitant chronic medications. Among the 9,838 patients (mean age 81.1 ±7.3 years; 61.1% female), 39.4%, 33.2%, 14.7%, 7.0%, 3.1%, and 2.5% demonstrated JARS scores of 0, 1, 2, 3, 4, and ≥ 5, respectively. Compared with JARS = 0, adjusted odds ratios (aORs) for laxative prescriptions were 0.85 (95% confidence interval [CI]: 0.76 -0.94,
