Effects of Increasing Concentrations of Rifampicin on Different Mycobacterium tuberculosis Lineages in a Whole-Blood Bactericidal Activity Assay.
Article in Antimicrobial agents and chemotherapy, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled 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.
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
High-dose rifampicin improved bactericidal activity and culture conversion in early-phase tuberculosis (TB) trials, done mainly in Africa. We performed a whole-blood bactericidal activity (WBA) study to determine whether the effects of high-dose rifampicin differ across globally relevant TB strains and whether effects are similar in dormant bacilli that will be required for enhancing cure. Whole blood from healthy volunteers was spiked with rifampicin (range, 0.63 to 60 mg/L) and incubated with one of four Mycobacterium tuberculosis clinical strains (Haarlem, Latin American-Mediterranean [LAM], East African-Indian [EAI], and Beijing lineages) or a dormant strain (streptomycin-starved 18b [ss18b]). Change in bacterial CFU was estimated after inoculation of WBA cultures in MGIT. WBA increased with higher concentrations of rifampicin in all strains. At rifampicin concentrations up to 5 mg/L, the rates of increase in WBA per unit increase in rifampicin concentration were similar in all 4 clinical strains (
