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

BACKGROUND AND

objectiveTherapeutic drug monitoring (TDM) typically uses total drug concentration (C

methodsA validated LC-MS/MS method used Centrifree ultrafiltration (CF-UF) for free RFPT isolation and isotope internal standard (rifapentine-d8) for quantification. Validation included specificity, linearity (3.00-299.60 ng/mL), accuracy, precision, matrix effects, and stability. Clinical samples from 58 patients with TB (adults and children) receiving RFPT were analyzed. Total and free RFPT, albumin, and biochemical parameters were compared.

resultsThe method showed excellent linearity (R

conclusionsThe LC-MS/MS method is rapid, sensitive, and suitable for routine free RFPT TDM. Nonlinear C
