Cutaneous reactions during treatment with Nifurtimox or Benznidazole among Trypanosoma cruzi seropositive adults without symptomatic cardiomyopathy: A safety sub analysis of a placebo-controlled randomised trial.
Trial report in Tropical medicine & international health : TM & IH, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02369978 (Cardiovascular Health Investigation and Collaboration From Countries of America to Assess the Markers and Outcomes of Chagas Disease), which is not on this map.

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.

Abstract
objectivesTo determine, in a randomised placebo-controlled trial, if cutaneous adverse reactions during treatment (CARDT) with Benznidazole occur as often as with Nifurtimox, and whether the dose and duration of treatment change that frequency.
methodsWe conducted the EQUITY trial (NCT02369978), allocating Trypanosoma cruzi seropositive adults with no apparent clinical disease to a 120-day, blinded treatment with Benznidazole, Nifurtimox, or Placebo (ratio 2:2:1). Active treatment groups included either 60-day conventional-dose (60CD) regimens (Benznidazole 300 mg/day or Nifurtimox 480 mg/day, followed or preceded by, 60 days of placebo) or 120-day half-dose (120HD) regimens (Benznidazole 150 mg/day or Nifurtimox 240 mg/day). CARDT had blinded adjudication as moderate to severe during the follow-up visits.
resultsAmong 307 participants, 42 CARDT (17.1%, 95% confidence interval [CI] 12.6-22.4) occurred in 246 receiving active treatment, compared to two CARDT (3.3%, 95% CI 0.0-11.3) in 61 participants receiving placebo. In 122 patients treated with Benznidazole, there were 31 CARDT (25.4%, including eight severe), compared to 11 CARDT (8.9%, including four severe) in 124 individuals treated with Nifurtimox (p < 0.001). Among the 125 participants assigned to the 120HD regimen, there were 26 CARDT (20.8%, including six severe), compared to 16 CARDT (13.2%, including six severe) among 121 in the 60CD group (p = 0.005). The agent-regime interaction was not significant (p = 0.443). Eleven participants (25%) with CARDT did not complete their treatment.
conclusionCARDT occurred more frequently with Benznidazole treatment, particularly with longer exposure despite the half-dose regimen. Clinicians should consider these differences when discussing treatment options with patients receiving nitro derivative agents.
